Abstract

PURPOSE:To make the storage density, the peripheral speed, and the quality of each track uniform and to improve the reliability, by connecting both ends of a tape-shaped storage medium to make an annular medium. CONSTITUTION:The storage medium is an annular medium 27. Two roller bearings 2 hold the annular medium 27 between themselves horizontally to rotate the annular medium 27. A magnetic head 7 is positioned on each track by a carriage 8 to record and reproduce information.
