Abstract
A magnetic recording and/or reproducing apparatus includes a single main slide member for interlocking the respective portions of a deck, a master gear member for moving the main slide member and a motor for driving the master gear member. The master gear member is engaged with a rack formed on the main slide member. The deck and a loading device for loading a cassette onto the deck are sequentially driven by the motor. The rack allows for mechanically stable operation and rapid mode change.
