    摘要： A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. The reel has a reel hub in the form of a cylindrical member which has a bottom wall and is provided with an opening and a stopper gear formed on the bottom wall. A brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear is brought into engagement with the stopper gear to prevent rotation of the reel and a retracted position where the brake gear is disengaged from the stopper gear to permit rotation of the reel. The brake member is normally urged toward the operative position and moved to the retracted position by a pusher member of a tape drive system which acts on the brake member through the opening in the reel hub when the magnetic tape cartridge is loaded in the tape drive system. A continuous wall portion is erected around the opening in the reel hub, and the brake member includes a horizontal portion and a continuous skirt portion which extends downward from the horizontal portion and is in contact with the continuous wall portion of the reel hub to close the opening together with the horizontal portion. The brake member is moved between the operative position and the retracted position with the skirt portion kept in contact with the continuous wall portion of the reel hub.

    摘要： A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. A brake member of the magnetic cartridge is provided with a brake gear and is movable up and down between an operative position and a retracted position. The reel is provided with a reel gear which is brought into mesh with a drive gear of a tape drive mechanism and a through hole through which a push rod extending from a brake release member projects to be brought into abutment against the drive gear of the tape drive mechanism so that the brake release member moves the brake member to the retracted position. The through hole opens in an area which is slightly wider than tips of teeth of the reel gear, wherein the area includes a pair of opposed flanks of the reel gear which form a valley.

    摘要： A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. A brake device including a brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear prevents rotation of the reel and a retracted position where the brake gear permits rotation of the reel. The reel is provided with a through hole through which a push rod extending from the brake release member projects to be brought into abutment against the drive gear of the tape drive mechanism so that the brake release member moves the brake member to the retracted position. The through hole and the push rod are in contact with each other by way of fine protrusions formed at the push rod or the through hole.

    摘要： A magnetic tape cartridge has a thin cartridge casing having flat upper and lower surfaces and a single reel around which a magnetic tape is wound. Projections are provided on at least three places of the lower surfaces of the cartridge casing near the leading edge and the trailing edge of the cartridge casing and recesses, which can engage 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 are engaged with each other, whereby the magnetic tape cartridges are prevented from being displaced with respect to each other when they are stacked and the sliding resistance when the magnetic tape cartridge is inserted into a recording and reproducing apparatus is reduced.
