ABSTRACT:
Data storage apparatus stores and retrieves data on tape, using a helical scanning write/read technique with data being stored in tracks of predetermined format written across the tape, for example in accordance with the DAT format. The apparatus comprises a data organizer for organizing data to be stored into frame units, each corresponding to two tracks' worth of data, and for disassembling data out of the frame units upon data retrieval; and a formatter for processing data received from the data organizer into the track format for writing to tape during data storage, and for reversing this process during data retrieval. Constituent data elements from each frame unit are interleaved with each other across two tracks when written to tape. To minimize the processing propagation delay and memory requirements of the formatter, transfer of data between the data organizer and the formatter is effected on a track-by-track basis, rather than on the basis of frame units, with the transfer of data in respect of one track being completed before transfer of data in respect of the next track is commenced.
