Abstract
A mode reset method for a magnetic recording/reproducing apparatus whereby a deck is preferably reset to a predetermined mode of operation when power is applied. The method includes an initializing step and a mode reset step. Preferably, the initializing step includes substeps for driving a plunger, rotating a capstan motor to connect a transmission gear to a loading system when the power is applied, and then retracting the plunger. The mode reset step includes substeps for resetting the deck to a stop mode when the deck is in the stop mode, when the deck is between the stop mode and a playback mode, or when the deck is between the stop mode and an unloading stop mode at the time power is applied. Alternatively, the mode reset step resets the deck to the unloading stop mode, when the deck is stopped between the unloading stop mode and eject mode. During the mode reset step, operation is controlling responsive to frequency generator signals during rotation of the capstan motor, and the outputs from stop and a cassette-in sensors. The mode reset method advantageously enables the deck to recognize its own mode of operation and to prevent malfunction thereof when the power is applied. …
