IPC: G11B15/14
Filed: 1989-03-30
Abstract: PURPOSE:To lessen malfunction by storing a count value at the time when the change-over of a magnetic head is executed in a steady state previously in a register, and computing the count value and a set value, and sending a computed result to a change-over signal generating part, and supplying a change- over signal generated according to the computed result to each magnetic head. CONSTITUTION:A computing part 10c in a CPU 10 executes computing operation between sampling count values n0, n1, etc., and constants A, B, etc., set beforehand, and the rise-up of the magnetic head change-over signal is controlled according to the computed result. For instance, a timer value t01 to control the falling of a head F is obtained by the multiplication of the count value n0 and the constant A, and the timer value t02 to control the rising of the head D is obtained by the multiplication of the count value n1 and the constant B. After that, the timer value obtained by the CPU 10 is sent to a timer 11, and at the point of time when the timer value reaches the set value, the head change-over signal is sent from the CPU 10 so as to change over the head. Thus, even though the rotation of a rotary cylinder is not settled, change-over can be ensured.

When electrons existing in the (r) valley in the GaAs quantum well layer 12 enter the AlGaAs barrier layer 13a of indirect transition type, the quantum mechanical coupling is applied to the electrons. As a result, the tunnel current accompanied by valley coupling is remarkably restricted, and the valley current concerning the collector current vs. base emitter voltage characteristics is extremely decreased, so that an superior peak to valley ratio is obtained.
