Magnetic recording and reproducing device

Abstract

Abstract PURPOSE:To attain the monitoring and checking of recorded information with a simple constitution by providing closely the 1st and 2nd heads, reproducing a signal recorded by the 1st head by the 2nd head, and recording a comparison output signal between this reproducing signal and the original signal to be recorded, by the 1st head. CONSTITUTION:When a head 43 records a signal on a track 50, head 44 reproduces the signal while following the head 43. Then a reproducing signal is amplified by a reproducing circuit 61 and fed to a comparator circuit 62. A comparison circuit 62 compares a recording signal by the head 43 reproduced by the head 44 and the original data from an original data recording circuit 63 and if a difference exists between the both, the head 43 records a signal representing an error signal of the track 50 into an area 50a by the indication of a comparison circuit 62 and records the signal on the track 51 again. Moreover, the same data is recorded on one track and also the adjacent track independently of the repetitive recording by the said monitoring at the record for error correction at reproduction.
