ABSTRACT:
The invention relates to a method for controlling the data transfer between the rotary memory device such as a disk drive apparatus and the central processing unit. In this invention, after positioning to the read start location designated by a command from the central processing unit for determining the read start location, pre-fetch of the buffer operation is started without waiting for the read command subsequent to that command.
