Abstract

PURPOSE:To install a rotating magnetic head means in a rotary case in the magnetic tape memory and arrange so that the circumference of this rotary case may rotatea t the same speed as the tape, thus enabling either writing or reading even the speed of while the tape is accelerated or reduced or the tape is stationary.
