ABSTRACT:
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.
