ABSTRACT:
A magnetic tape cassette has a casing body which contains a magnetic tape and is provided in the bottom thereof with an opening through which a tape loading mechanism of a recording and reproducing system is inserted into the casing body, and a slider provided opposed to the lower surface of the casing body to be slidable in the direction of loading of the magnetic tape cassette between a closing position where it closes the opening and an opening position where it opens the opening. A resilient locking piece is provided on the bottom of the casing body and a pair of through holes which are brought into engagement with the resilient locking piece respectively in the closing position and the opening position of the slider to lock the slider there is provided on the slider. A guide channel is formed on the side of the slider remote from the casing body to extend in the direction of loading of the cassette in order to guide a lock release member of the recording and reproducing system to disengage the locking piece from the through hole. An elevated area is formed on the slider facing and in sliding contact with the lower surface of the casing body. The elevated area is formed so as to surround the area corresponding to the guide channel and extends from the front end of the slider to or short of the middle between the ends of the slider.
