Abstract

PURPOSE:To shorten a rotation waiting time and an access time by starting a read action from a sector that is first detected after a data read instruction is supplied. CONSTITUTION:When a data read instruction signal 114 is inputted from a host processor, a controller 19 outputs a disk control signal 108 and a track buffer control signal 113 to start reading data equal to one track length, and outputs a load signal 109 upon detecting a sector zero detection signal 107 to load the counting value of a counter 14 at the time of sector-zero-detection in a register 15. The controller 19 also detects the end of the reading of a sector equal to one track length by means of a coincidence signal 112, and informs the host processor of that data on the track buffer 11 is valid by means of a buffer read able signal 115, further, the controller 19 permits the address converting operation of an address converter 16 by means of an address conversion control signal 110, so that the sequence shifts to a data read mode from the track buffer 11. As a result, an access time can be shortened.
