Abstract
PURPOSE: To enable an accurate read by a tape recorder different from that for data writing by making a decision between 1 and 0 of data from the pulse width of reproduced initial data and then by judging the numbers of continuous data 1 and 0.
CONSTITUTION: Through pulse-measuring circuit 32 and I/O decision circuit 33 of initial synchronizing data reader 3, reproduced initial data read out by tape recorder 1 is judged data [1] when the pulse width is twice or data [0] when once, and continuous data 1 and 2 are counted by counter 34. When those count values are judged 18 and 36 by comparing decision circuit 35, the final detection pulse is stored in memory 36 by a coincidence signal outputted by circuit 35 to position the beginning of data recorded in the form of a one-bit one-cycle waveform, so that even if the reproduced initial data read out by a tape recorder of a different kind from that for writing would have been inverted, data can be read out with accuracy.
