Abstract

PURPOSE:To read and write information recorded on the surface of rods, by arranging some rod-shaped storage media in flat and rotating each rod. CONSTITUTION:A radius of a known magnetic disc is taken as (r), then the area useful for the storage is limited to about a half at the outside and the surface area is 3/4pir<2>. Taking the radius of a rod as (r'), the surface area per one rod is 4pirr', and when (n) pieces of rods are used with arrangement corresponding to a diameter of the disc, the entire surface area is 4pir<2> and the storage capacity is about 5.3 times. A multiplex stick plate is constituted shown in figure, the same as the usage of a magnetic disc, the surface of the rods is magnetized or grooves or holes are made on the surface for the purpose of storage.
