Abstract

PURPOSE:To achieve the increase in capacity per unit and the improvement in the reliablitlity of the information of a stationary head by using a cylindrical or disc form recording medium whose circular faces and circumferential face are respectively recorded and reproduced. CONSTITUTION:A movable magnetic head 7 is provided on the circular faces of a cylindrical or disc form recording medium 28 whose circular faces and circumferential faces are recorded and reproduced, and a stationary head 23 is provided on the circumferential face of the medium 28. This enables the head 23 to be used without reducing the track regions used by the head 7. Further the head 23 concerns with the outermost circumferential face and therefore the problems of capacity per unit and prices may be solved and the reliability for the quality of information enhanced.
