ABSTRACT:
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 F.sub.n is generated, files which were originally stored in the cassette memory following the n-th file F.sub.n are stored successively and in block-by-block fashion in the cassette memory starting from the position at which the n-th file F.sub.n was originally stored.
