Abstract

PURPOSE:To get rid of a defect generating a time difference between each data, and to hold simultaneity of each data, by inputting a correcting pulse signal to each channel, and detecting a time difference of its pulse signal after reproducing. CONSTITUTION:A pulse outputted from a correcting pulse generating circuit 6 is outputted at an optional time interval, and is applied to a distributing circuit 7 which generates no time difference. A pulse from the circuit is superposed on each data from a terminal 8, and is recorded in a recording data recorder 5. A data signal from a reproducing long play data recorder 9 is converted to a digital signal by an A/D converter 10 at first, and is applied to a delaying circuit 11. A correcting pulse is fetched by a time difference measuring circuit 12, in which a time difference is detected, this time difference is provided to the delaying circuit 11 as a control signal, a data signal from the converter 10 is controlled, and loss of simultaneity of a data due to non-alignment of a gap of the head is recovered.
