Filed: 1985-04-30
Abstract: PURPOSE:To apply sufficient focusing in the range of focusing for the head itself by providing a head position variable means changing the position of the head main body to an information storage medium. CONSTITUTION:The information storage medium 22 is arranged oppositely to the head main body 21 and driven rotatingly by a rotation driver 23 with a constant line velocity.
