ンタとを具備してなるデータレコーダ。[Claims for Utility Model Registration] Used in an external storage device for a computer, the recording head records recorded data from the computer onto a magnetic tape running at a running speed V; The magnetic tape is provided at a predetermined distance L in the tape running direction or longitudinal direction, and performs a reproducing operation to reproduce recorded data recorded on the magnetic tape at the same time as the recording operation of the recording head, and outputs the reproduced output as reproduced data. a playback head and a time at which recording data is recorded on the magnetic tape (
a buffer that outputs the recorded data after T time (=the predetermined distance L/the magnetic tape running speed V) has elapsed from the recording time); ) and a comparison circuit that compares the playback data output from the playback head and outputs a match output when the recorded data and the playback data match, and outputs a mismatch output when they do not match; A data recorder comprising: a counter that calculates the number of mismatches between the two pieces of data, and outputs an error signal when the number of mismatches is equal to or greater than a predetermined number.
