摘要： A rotary head type recording or reproducing apparatus of the type in which the recording or reproduction of signals is effected by tracing a recording medium transported in a predetermined direction with rotary heads in a direction which is at less than 90.degree. with respect to this predetermined direction. The apparatus is provided with a rewinding mode in which the above-mentioned recording medium is transported in a direction reverse to the above-mentioned predetermined direction without performing the recording or reproduction of signals, with the rotary heads being in the condition where they can trace the recording medium. In this rewinding mode, the rotary heads are rotated in a direction reverse to their rotating direction during the recording or reproduction of signals.

摘要： In a magnetic recording and reproducing apparatus for recording and reproducing information by pulling out a tape from a cassette by revolving a pair of tape pull-out members in opposite directions with a tape loading mechanism and by wrapping the tape around a rotary drum, a tape pull-out aiding member is arranged in combination with one of the tape pull-out members; and a differential mechanism is arranged between the tape pull-out aiding member and the tape pull-out member to cause the two members to revolve at different angles of revolution in such a way as to give a desired angle of inclination of the tape relative to the rotary drum. The differential mechanism is formed jointly by a slide member which is slidable in the direction of revolution, the tape pull-out aiding member being disposed at the slide member, and a positioning member which is arranged to lock the tape pull-out aiding member by restricting its movement in such a way as to cause two members to revolve at the different angles of revolution.
