Abstract
An information storage device randomly accesses data items in a sequential access storage medium. A controller, upon loading of the sequential access storage medium, causes the blocks of data items in the sequential access storage medium to be copied to corresponding blocks on the random access storage medium whose correspondence is established by the table. A table establishes the correspondence between blocks of data items in the random access storage medium and blocks of data items in the sequential access storage medium. Upon receiving an instruction from a host computer, the controller further performs a series of read/write operations on the blocks of data items in the random access storage medium. The overwritten blocks of data items on the random access storage medium are updated to the corresponding blocks on the sequential access storage medium.
