Abstract

PURPOSE:To shorten the access time, by outputting the head load signal to the FF from the floppy disc controller (FDC) on a basis of the read/write (RW) command and by outputting the direct head load signal to FDC by the next RW command to stop outputting of the head load signal. CONSTITUTION:When the read/write (RW) command is output from the CPU, floppy disc controller (FDC)1 outputs the head signal to set FF2. At this time, the first RW is executed. Next, when the second and following RW commands are issued in the same track, the output from the FF and the RW command are input to gate 3, and gate 3 outputs the direct load signal to FDC1. At this time, FDC1 does not output the head load signal, but FF2 continues outputting the load signal; and when this outputting is terminated, FF2 is reset by the head unload command. As a result, the access time is shortened to improve performance as the whole.
