Abstract

PURPOSE: To reduce the loss of set-up time of continuous read/write instructions and improve the processing speed by programmably delaying the head unload time after access.
CONSTITUTION: When a read/write instruction is executed, a head loading signal is emitted from an OR 2 and the head is loaded. At the same time the value having been set in the program of a register 4 is set in the counter 3, and FF 1 is also set. Even if this instruction is finished, the FF 1 is held set and therefore the head is held loaded, during which time, it may be set as desired by changing the value of the registre 4. At this time, a continuous read/write instruction is given and if it is before the counter 3 becomes "0", the head is held loaded and therefore the read/ write may be continued without taking head set-up time. Thereby, processing speed is considerably improved.
