发明名称 Signal reproducing device which offsets the tracking error signal
摘要 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.
