摘要： The actual data recording area on a recording medium is expanded by reducing a gap area between blocks of data for compensating for a delay time of data conversion while recording and reproducing data in a data recording and reproducing device. Based on a servo sector signal, a data sector generator circuit generates a write data sector signal indicating a timing of data recording in a data recording area, and outputs the write data sector signal to a delay circuit and a selector having two input ports and one output port. The delay circuit generates a read data sector signal by delaying the write data sector signal by a certain period, and outputs the read data sector signal to the selector. The selector outputs the write data sector signal when a write mode signal is active, and outputs the read data sector signal when the write mode signal is inactive.

Secondary, in a signal processing or in a recording and reproducing apparatus, reliability of data reproduction is improved by repeatedly processing data.

The apparatus includes a signal processing circuit to repeatedly process the stored digital signal in the secondary storage. When detecting data, operation of the circuit is efficiently controlled by a change over detector parameters, in which characteristics for the detecting performance. Resultantly, data recovery processing speed is increased and reliability of data reproduced is improved.

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 provide a disk drive that is capable of effectively controlling a side erase, which is one of the problems with the use of the perpendicular recording technology. In one embodiment, tracks on a recording medium are formed concentrically or spirally by overwriting a primary side track, which is either an inner track or outer track, onto part of a secondary side track, which is on the side away from the primary side track. A head unit is installed so that a magnetic head positioned at one end of the head unit relatively may move over the recording medium and that the yaw angle prevailing at an end track of the primary side on the recording medium may be substantially zero.

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.
