File deletion method for bubble cassette memory, and bubble cassette memory control apparatus.

摘要

A method and apparatus for deleting a file from a bubble cassette memory. A file, constituting one input unit of data to be written into the cassette memory, is divided into a plurality of blocks each comprising a predetermined number of bytes and is thereafter stored in the cassette memory. In similar fashion a plurality of such files are stored in the cassette memory in numerical order. When a command for deletion of the n-th file Fn is generated, files which were originally stored in the cassette memory following the n-th file Fn are stored successively and in block-by-block fashion in the cassette memory starting from the position at which the n-th file Fn was originally stored.
