摘要： A data processing method of recording data on a recording medium mounted on an information recording apparatus. The data processing method includes the steps of dividing, in a disk controller, parallel data constituted by p bits transferred from a high-rank device into data each having q bits, where p and q are numbers; transferring the data each having q bits from the disk controller to an encoder as parallel data constituted by q bits; encoding, in the encoder, the data each having q bits to generate recording signals corresponding to data to be recorded; and recording the recording signals on the recording medium, thereby recording the data to be recorded on the recording medium. The data processing method may further include the steps of reproducing, from the recording medium, the recording signals recorded on the recording medium; decoding, in a decoder, the reproduced recorded signals to generate data each having p bits; transferring the data each having p bits from the decoder to the disk controller as parallel data constituted by p bits; and converting, in the disk controller, the data each having p bits into parallel data constituted by m bits to be transferred to the high-rank device, where m is a number.

摘要： In a signal processing unit for writing/reading data on/from a disk-shaped recording medium of a disk apparatus, all of a data separator, a code decoder circuit, a code encoder and a write compensation circuit are constructed on a one-chip integrated circuit. The data separator separates a synchronization clock from a code data reproduced from the disk. The code decoder circuit produces decoded data from the synchronization clock as the output from the data separator, and synchronized code data. The code encoder encodes data supplied from a host computer or a disk controller into code data. The write compensation circuit compensates for a peak shift with respect to write code data. This integrated circuit is fabricated by a Bipolar-CMOS process by which a bipolar transistor and a CMOS transistor are mixed with each other thereon.
