Abstract
With a magnetic record and playback device that permits rapid switching from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode, when it is necessary to switch rapidly from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode, the device is operated in a first take-up mode in which magnetic tape is wound on the rotating head drum, and when it is not necessary to switch rapidly from fast forward (FF) mode or rewind (REW) mode to playback (FWD) mode but is required to increase magnetic tape transport speed, the device is operated in a second take-up mode in which the magnetic tape is not wound on the rotating head drum, whereby it is possible to shorten the fast forward/rewind time by raising the transport speed of the magnetic tape without increasing the load on the magnetic tape or the magnetic head.
