Abstract:
A magnetic tape reproduction apparatus for reproducing a magnetic tape containing a plurality of binary data constituting various mark patterns which are recorded in parallel on a plurality of data tracks and repeated in serial, the apparatus comprising:a tape drive block for linearly moving said tape;a data reproduction block for reading the plurality of data tracks in parallel and successively reproducing the binary data from the respective data tracks;a mark detection block for successively identifying as a plurality of mark patterns, a plurality of parallel binary data successively reproduced in serial by the data reproduction block, and when a mark pattern is identified, makes the enable signal Hi for the corresponding mark;a differentiation circuit provided for each of the mark pattern types so as to detect a rise of the enable signal of a corresponding mark produced from said mark detection block, and outputting a differentiation signal; anda microprocessor for identifying a mark pattern according to the reproduction time of the enable signal and the output of the differentiation circuit.
