Abstract A signal reproducing device for an R-DAT employing offsetting of the tracking error signal in which the digital error rate is significantly reduced. A head assembly traces tracks on which predetermined digital data and tracking pilot signals have been recorded, the head assembly having a larger tracking width than the tracks. The pilot signal is detected from the reproduction output of the head assembly to form a tracking error signal. The level of the RF signal reproduced by the head assembly is detected and is compared with predetermined reference values. An offset signal is added to the tracking error signal according to the comparison result. A servo circuit controls the tracking conditions of the head assembly according to the addition result.
A signal reproducing device comprising: a head assembly for tracing tracks on which predetermined digital data and tracking pilot signals have been recorded, said head assembly being larger in tracking width than said tracks; first detecting circuit means for detecting a pilot signal from a reproduction output of said head assembly to form a tracking error signal; second detecting circuit means for detecting the level of a signal reproduced by said head assembly; a comparing means for comparing an output of said second detecting circuit means with predetermined reference values; means for adding a predetermined offset signal to said tracking error signal according to an output of said comparing means; and a servo circuit for controlling tracking conditions of said head assembly according to an output of said adding means.
