摘要： A liquid crystal display device providing a multi tone control function is disclosed, permitting a multi-colored display to be provided by using an analogue display data input, while regulating stepwise the brightness by varying the level of the applied voltage. The liquid crystal display device is composed of serial/parallel converter having a high sampling speed, into which liquid crystal display data are inputted, with a function of converting serial image data into parallel image data, and an X axis direction driver having a low sampling speed, into which the liquid crystal display data for one pixel are inputted, with a function of outputting the liquid crystal display data of one line in the horizontal direction, synchronized with a display line signal for a Y axis direction driver. The S/P converter and the X axis direction driver are disposed separately. Further the S/P converter and the X axis direction driver are constructed so as to hold analogue quantities in order to output the liquid crystal display data applied to the liquid crystal driving elements constituting the pixels of a liquid crystal display panel in the form of analogue signals. In this way a multi-colored display of not less than nine colors, using an analogue input, can be effected, and it is possible to display arbitrarily levels of brightness by varying the level of the applied voltage.

摘要： Count pulses CTP from a counter 15 are supplied to a phase detector 3 through a two-frequency-divider 17 to produce measurement data N.sub.1 representing a difference in phase from a synchronized peak pulses PK. In a subtractor 4, the measurement data N.sub.1 is compensated with error data Ne from a register 13 in order to reduce the number of steady-state phase errors. An internal phase error .DELTA.N produced by the subtractor 4 is supplied to an LPF 5, undergoing compensation processing in a digital filter 7 thereof. The LPF 5 also includes a phase compensator 6 and a period compensator 8 for compensating a control delay experience by the internal phase error .DELTA.N in the digital filter 7. An integer part OPD1 of counter oscillation period data OPD output by the LPF 5 is used for determining an oscillation period of a counter 15 whereas a fraction part OPD2 thereof is accumulated in a register 12 through an adder 11. An error accumulated in a register 12 is transferred to a register 13 and stored therein as error data Ne. Accordingly, the acquisition time is shortened and the number of steady-state errors is also reduced as well.

摘要： In accordance with a write address successively updated in synchronism with a dot clock, color display data is written into a memory. The memory includes three memory corresponding to three primary colors and having identical addresses thereto assigned. For the purpose of color display, the written display data is read out three times consecutively during one write clock interval. A read address generator for supplying a read address successively changed to the memory is reset when addresses have been generated up to the number of horizontal display dots. The resetting is performed when the number of horizontal display dots detected from the dot clock and a display timing signal has coincided with a read address signal outputted from the read address generator. Since the reset timing of the read address generator changes according to the number of horizontal display dots detected by horizontal display dot number detector, it is possible to cope with a change of the personal computer supplying input data without changing the circuit.

摘要： When the format control circuit detects bit synchronization information in a sector to be reproduced on a magnetic disk, the format control circuit activates a read gate signal for commanding to read out the sector from the magnetic disk. When symbol synchronization information on the magnetic disk is detected, a SYNC detection circuit produces a synchronization information detection signal. The format control circuit calculates an end position of the sector on the magnetic disk on the basis of the synchronization information detection signal to inactivate the read gate signal. The data correction circuit and the decoding circuit reproduce data and ECC in the sector read out from the magnetic disk during the period that the read gate signal is active on the basis of the synchronization information detection signal to produce the data and ECC to a data bus. The data flow control circuit processes the data and ECC on the data bus after the elapse of a reproduction delay time on the basis of the synchronization information detection circuit.

摘要： A method for writing data to a disk drive. The method includes: receiving a write command; and, determining whether a beginning and an end of a rewrite area specified by the write command agree with boundaries of large-sized data sectors on a disk. The method also includes: reading head and tail data sectors and making a backup of the head and tail data sectors in first and second non-volatile memory areas, respectively, if the beginning of the rewrite area does not agree with the boundaries. The method includes starting a rewrite of the rewrite area after completing backups into first and second non-volatile memory areas. Moreover, the method includes: determining a state stage by using data in first, second, third and fourth non-volatile memory areas if a power shut-down occurs during execution of the write command; and, executing a recovery process in accordance with the determined state stage.

摘要： Embodiments of the invention provide a disk drive that is capable of determining the offset of a magnetic head position through simple and easy processing in a case where the shingle write method is adopted, and that is capable of increasing the accuracy. In one embodiment, a disk drive comprises: a recording medium including data tracks, each of which is formed with part of the data track being overwritten by an adjacent data track on the inner circumferential side or by an adjacent data track on the outer circumferential side; a head assembly including a write head for writing information to the recording medium, and a read head for reading out information from the recording medium; and a control device for controlling a position of the head assembly relative to the recording medium. Position-error detection signals whose phases differ from each other are repeatedly written to the recording medium in the track direction with written positions of the position-error detection signals being deviated from each other by a track pitch in the track width direction; and the control device controls a position of the head assembly on the basis of a burst signal read by the read head.

摘要： Embodiments of the invention increase the convenience of a magnetic disk drive for portable use by shortening a period of time required to record a large amount of data, and by increasing the reproduction time, in the magnetic disk drive. In one embodiment, an area between servo data parts is interpolated by servo data parts, each of which stores a burst signal, so that the allocation density of a burst signal is made k times. At the time of write operation in which data is written, only the servo data parts are made use of to perform the servo control while a disk is driven at high rotational speed so as to reduce the recording time. At the time of read operation in which data is reproduced, the servo data parts are made use of to ensure the required precision of the servo control at low rotational speed that is 1/k of the rotational speed at the time of write operation. The reproduction at low rotational speed enables the reduction in power consumption.

摘要： In one embodiment, a symbol error correction encoder effects block interleaving on recording data and thereafter performs first error correction encoding on the recording data. Next, a symbol error correction encoder performs encoding on the whole block. A reproducing processing circuit outputs likelihood information of respective bits. A first error correction decoder corrects a random error produced upon recording and reproduction, using the likelihood information. Since it is possible to make an improvement in performance with respect to the random error by repetitive decoding at this time, the post-correction data is returned to the reproducing processing circuit. After the completion of such repetitive processing, the data is digitized and subjected to an error correction in symbol unit by a hard determination, and outputted to a symbol error correction decoder.

摘要： Embodiments of the invention a signal processing method capable of realizing low decoding error ratio by using a simple configuration free from unnecessary redundant bits. In one embodiment, user data (512 bytes+additional data) input to an input terminal is RLL-encoded by a RLL encoder 1. The data from the RLL encoder—1 is entered into a symbol error correction encoder where 9-bit symbol encoding is done. Its RS code portion is RLL-encoded by a RLL encoder—2. Signal read from a magnetic disk is entered into a RLL decoder—2 where the RS code portion is RLL-decoded. The signal from the RLL decoder—2 is then entered into a symbol error correction decoder where random read/write errors, burst errors attributable to defects and other errors are corrected to produce a (user data+RLL) signal. This data is output to an output terminal after being decoded by a RLL decoder—1.
