Information recording-reproducing head driving circuit

Abstract

An information recording-reproducing head driving circuit for moving an information recording-reproducing head from the current position on a recording medium to a desired position while velocity-controlling the head includes a pulse motor for moving the information recording-reproducing head relative to the recording medium, a timer for counting down a count value set to take the driving timing of the pulse motor, and controller for calculating the count value on the basis of a predetermined time table and setting the count value in the timer, and generating a driving pulse to the pulse motor when the timer has counted down the count value. The controller substracts a desired value extracted from the time table from the count value set in the timer the last time to thereby accomplish the calculation of a new count value.
