Large capacity information storage apparatus using a plurality of magnetic disk unit.

摘要

An information storage apparatus (20) used in combination with an information processing device utilizes a plurality of magnetic disk units (22). The units are individually stocked in stocking locations of a stocking device (23). The stocking locations are assigned with different address numbers. On receiving an incoming signal from the information processing device, one of the units is loaded into a disk driver (24) by a transporting device (49, 50) and a desired information data is recorded or reproduced on a flexible magnetic disk of the unit. The one of the units is thereafter returned to the initial location of the stocking device. Each of the units may have a recording medium. A recording and reproducing device (57) records or reproduces address information on the medium of the unit during transportation of the unit, so that a series of information data can be recorded over more than one units and can be recorded therefrom without false.
