Title: Magnetic recording and reproducing device
Inventor: YAMAZAKI SHOHEI
IPC: G11B15/467
Filed: 1987-03-10
Abstract: PURPOSE:To stably read a bit of recording information on a magnetic tape at the time of fast-feeding or rewinding the tape at arbitrary speed, by forming a speed control servo loop so that a pilot signal can be detected with almost a regulated frequency. CONSTITUTION:When the pilot signal is detected at a low-pass filter 164 and relative speed is changed, the frequency of a detected pilot signal is also changed, however, by setting the cut-off frequency of the low-pass filter 164 at around 200kHz, the pilot signal can be surely extracted. A pilot frequency detection circuit 172 detects the frequency of an extracted pilot signal, and detects an error between a regulated value of frequency, and a relative speed error signal is inputted to at least either a reel servo 122 or a drum servo 118. And since the relative speed is controlled at the regulated value by controlling at least either a reel motor 44 or a drum motor 28 so that the frequency of the pilot signal can be set at the regulated value, it is possible to reproduce a head output signal. In such a way, it is possible to read a bit of sub code information stably.
