Title: Magnetic tape recording/reproducing device
Inventor: TEZUKA YASUSHI
IPC: G11B15/467
Filed: 1989-11-17
Abstract: PURPOSE:To smoothly shift a system to a same mode by forming the servo of a phase control system lest operates for preventing shift control from a different mode to the same mode at the time of executing it. CONSTITUTION:When a different mode discrimination circuit 10 discriminates it to be the different mode based on a control signal inputted to an input part 10a, a different mode signal IMS is outputted from an output part 10c to a muting transistor 17 so as to turn it on. Furthermore, the signal IMS is outputted to a muting transistor 21 from 10e so as to turn the transistor on. Consequently, positive or negative servo control from the phase control system is prevented at the time of outputting the signal IMS, controlling the rotation of a capstan servo motor 6 and setting the system to be the same mode. Thus, shift for the same mode is smoothly attained.
