Information storage device comprising a magnetic tape recorder and a hard disc drive

摘要

An information storage device includes a sequential access storage medium (12) and a randomly accessed storage medium (11). Data from the sequential access medium is loaded to the randomly accessed medium. When an external device (1) accesses the information storage device, data is, in fact, accessed from the randomly accessed storage medium, even though, as seen from the perspective of the external device, the selected data is apparently accessed directly from the sequential access storage medium. <MATH>
