ABSTRACT:
A method for selecting a desired piece of information recorded in a magnetic tape mounted in a magnetic tape recorder and/or reproducer while reproducing the information, the magnetic tape recorder and/or reproducer having a magnetic head, a tape transport, and a mechanism controller adapted to actuate the magnetic head and the tape transport to perform selectively one of mode operations including PLAY, CUE and RVW mode operations. The method comprises a first step of causing the mechanism controller to perform the CUE or RVW mode operation while detecting the output signal from the magnetic head to find a leading edge of an information carrying tape portion, a second step of causing the mechanism controller to perform the PLAY mode operation which is initiated from a tape portion adjacent to and upstream of the leading edge of the information carrying tape portion for a certain period after finding the leading edge, a third step of causing the mechanism controller to repeat the first and second steps until a manual stop command is given during the period, and a fourth step of causing the mechanism controller to perform the PLAY mode operation even after the period in case a manual stop command is given during the period.
