ABSTRACT:
A disk drive control system using a disk controller enables a host processor system to issue a data read/write command to a disk controller before a disk drive is brought into an access-enable state. Since a pseudo-ready signal is fixed at the active level the host processor system issues the data read/write command to the disk controller. Once the data read/write command has been issued the host processor system can perform processes other than disk control.
