Device for rewriting control information in a disk drive

摘要

A control information rewritable disk driving device is provided with a disk rotation driver (32), a reprogrammable ROM (4) which stores control information therein, a general-purpose interface (6) which is selectively connected to an externally-provided host control device (10) and performs the transmission and reception of data to and from the host control device upon connection, and a CPU (2) for controlling the operation of each part according to the control information. When a control information rewrite command and new control information are supplied from the host control device (10) to the CPU (2) through the general-purpose interface (6) when the general-purpose interface and the host control device are connected to one another, the CPU renews the control information stored in the reprogrammable ROM to new control information. <IMAGE>
