  • Moving Of Head For Track Selection And Changing (AREA)

Abstract

PURPOSE: To move rapidly a magnetic head to a desired position on a track by providing the magnetic head with an additional access function of driving in the radius direction of a magnetic sheet.
CONSTITUTION: When access button 22 of the 2nd block is depressed while head 9 is in process of the reproduction of the 1st block, the microcomputer sends a signal to the power motor and turntable 7 stops at a specific turning angle. Next, the computer sends an electric feed signal to the plunger to lower head 9 and then access motor 39 turns on receiving a rotation signal. Then, the helical gear rotates and spiral shaft 30 also rotates to move head 9 in the radius direction of table 7. At this time, shutter part 45 of access pulley 43 cuts off the light of photocouplers 46 and 47 and the number of signals generated by photocouplers 46 and 47 is displayed on display unit 25 in addition to the number of signals generated by the leaf switch. When the number reaches a fixed value, the computer stops motor 39 and head 9 is elevated with the feed stop signal of the solenoid, so that access to the start position of the 2nd block will be attained.
