ABSTRACT:
A magnetic tape cassette incorporates therein a braking member which brakes reel hubs when the magnetic tape cassette is not in use, so that the reel hubs are prevented from being rotated. The braking member can be operated to release the reel hubs from their locked conditions from any side of the upper and lower parts of the cassette casing. Thus, the magnetic tape cassette of this invention can correspond with a tape cassette of the double-sided use kind, in which a cassette casing is turned over and the recording and reproduction can be performed in a cited fashion.
