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： An image formation apparatus includes a fixing heater, and a zero-cross detector that detects zero-cross points of a frequency of an alternating current (AC) power supply connected to the heater. The image formation apparatus also includes a controller that controls light-on of the heater by pulse-width-modulation (PWM)-controlling the frequency of the AC power supply, that controls a duty width of a PWM control signal for the frequency of the AC power supply for a half period that corresponds to a period between the adjacent zero-cross points detected by the zero-cross detector, and that controls an amplitude of an input current from the AC power supply so that a waveform of the input current becomes a rough approximation of a sine wave.

摘要： There is provided a magnetic disk drive in which the adaptability of read signal processing of the magnetic disk drive is enhanced so that the frequency of retry or miscorrection in use is reduced. This magnetic disk drive has a read circuit, and a channel condition measuring circuit. An output of an A/D converter contained in the read circuit is supplied to a digital equalizing circuit so as to be equalized accurately. Upon input of a signal for instructing a coefficient learning circuit to learn the coefficient of the digital equalizing circuit, the initial coefficient registered in a register is set as a coefficient value in another register and the coefficient learning circuit is operated to start consecutive learning of coefficient values. In the channel condition measuring circuit, errors in a row of output values of the digital equalizing circuit are calculated and an integrated value of squares of the errors is compared with an error threshold value. If the integrated value is larger than the error threshold value, coefficient learning is regarded as being abnormal and a control signal for discarding the coefficient registered in the register is issued so that the register is reset to the initial coefficient value. The signal for instructing the coefficient learning circuit to learn the coefficient may be outputted in a sector previous to the read target sector or may be outputted in the read target sector.

摘要： The equalizer is capable of generating an equalized output that is compensated in the non-linearity of the signal reproduced by an MR head and a reliable high-density magnetically recorded-signal reproducer. The equalizer of an FIR-type filter structure includes a plurality of delay elements for delaying an input signal by a certain period, a plurality of coefficient processing units provided to input or output taps of the delay elements, and an adder for obtaining the sum of the outputs of the coefficient processing units. The distortion of the reproduced waveform can be corrected by a relatively simple circuit structure by comparing the signal value inputted to the coefficient processing unit from each tap with a predetermined threshold level and changing the signal value and a coefficient value to be multiplied in accordance with the comparison result. Therefore, any one of various existing signal processing systems can be applied to the decoding of reproduced signals of an MR head having the non-linear characteristic.
