Title: Reproducing control method of rotary head type tape recorder
Inventor: TAKI TETSUYA
IPC: G11B15/467
Filed: 1985-01-19
Abstract: PURPOSE:To perform accurate reproducing control by extracting pilot signal components of two adjacent tracks from reproducing signals of the respective tracks during reproduction and detecting a tracking error from their level difference. CONSTITUTION:A pilot signal of the same frequency which is lower than that of a synchronizing signal is recorded in pilot areas of odd-numbered and even- numbered tracks on a tape. The width of a rotary head is set a little bit larger than track width and a playback signal is inputted to an input terminal 4 and further inputted to an LPF18 and a BPF7 through a reproducing amplifier 5. The output of the LPF18 is supplied to an envelope detecting circuit 11 and the level of the pilot signal of an adjacent track is extracted from a reproducing pilot signal. The BPF7, on the other hand, extracts the synchronizing signal and sampling pulses are sent to sample holding circuits 12 and 13 through a comparator 14 and a timing pulse generating circuit 15 to sample and hold the output level from the circuit 11, so that a tracking error signal proportional to the level difference pilot signals of adjacent tracks is outputted from an operational amplifier 16.
