ABSTRACT:
When a positioning operation of a head on a track of a disk including a target record is completed, information is read out from the track of the disk and stored in a buffer memory without waiting a read command from a host side controller. A transfer operation of the target record of the information from the buffer memory to the controller is performed when the controller is not busy and generates the read command. A transfer rate of the record from the buffer memory to the controller is made faster than a read rate of the information from a disk or a write rate into the buffer memory, so that a nominal transfer rate of an entire system is increased without changing the read or write rate.
