Abstract
In a magnetic tape cartridge comprising a thin cartridge casing having flat upper and lower surfaces and a single reel which is housed in the cartridge casing for rotation and around which a magnetic tape is wound, island-like or point-like projections are provided at least three places of the lower surfaces of the cartridge casing near the leading edge and the trailing edge of the cartridge casing as viewed in the direction X of insertion of the magnetic tape cartridge in a recording and reproducing apparatus and recesses which are adapted to be engaged with the projections are provided on the upper surface of the cartridge casing so that, when a plurality of the magnetic tape cartridges are stacked, the projections and the recesses of the cartridge casings of magnetic tape cartridges which are just above and below each other are engaged with each other, whereby the magnetic tape cartridges are prevented from being displaced with respect to each other when a plurality of magnetic tape cartridges are stacked and the sliding resistance when the magnetic tape cartridge is inserted into a recording and reproducing apparatus is reduced.
