Abstract
Abstract A magnetic reproducing apparatus of the cassette type or the like. The apparatus has a mechanism for automatically changing the tape transportation mode from the fast condition, such as the fast forward or rewind operation of one recorded track of the tape, to the slow condition, such as a playback operation of a different recorded track or a repeating playback operation of the same recorded track. The tape transportation mode is changed in response to a tape stoppage detecting mechanism.
