Abstract
A disc storage apparatus includes at least one disc having at least one recording surface, at least one head associated with the at least one recording surface for recording data on the at least one recording surface, a decoder circuit which receives coded data from the at least one head, decodes the coded data to parallel data, and outputs the parallel data, and a disc control unit which receives the parallel data from the decoder circuit and outputs the parallel data outside the disc storage apparatus. The apparatus may further include a host interface control unit coupled to a host computer and the disc control unit, wherein the disc control unit outputs the parallel data to the host computer via the host interface control unit, and a buffer memory which stores the parallel data to be outputted to the host computer.
