Abstract

PURPOSE: To place a magnetic head where it can read an address discriminating part at any time by putting the magnetic head in write and read operation while moving the magnetic head on a magnetic disk in revolution in its radius direction.
CONSTITUTION: Driving mechanism 2 turns magnetic disk 1 and when magnetic head 3 moves to a track position for write or read operation, inputting write/read request signal 6 sets FF circuit 8 by the 1st track starting-end detection signal 5 after the input of this signal 6 so as to output writable/readable signal 7, so that driving mechanism 10 will move connecting rod 9 and magnetic head 3 in the center direction of magnetic disk 1 at a fixed speed by signal 7. On the other hand, when signal 7 is input to control circuit 14, circuit 14 makes an address comparison between write/read address assignment signal 11 and address read signal 17 of an address discriminating part read by magnetic head 3 and when the both agree with each other, magnetic heads 12 and 12' are matched with information signals 13 and 13' to write or read address information.
