    Abstract: A data processing system uses a tape-containing cassette for interchange between low-speed recording systems and high-speed or high-performance recording systems. In a low-performance system, the tape is transported wholly within the cassette. The cassette may be removed from a low-performance player and placed in a high-performance player. Then, the tape is partially removed from the cassette for higher speed transport. Modifying the front end of the cassette enables it to be placed either in the lowperformance or high-performance unit enabling upward and downward compatibility. Modifications of the front end may be either manual or aoutomatic.

    Abstract translation: 数据处理系统使用含磁带盒来在低速记录系统和高速或高性能记录系统之间进行交换。 在低性能系统中，磁带完全在磁带内传输。 盒式录像带可以从低性能播放器中移除并放置在高性能播放器中。 然后，磁带部分地从盒中取出以进行更高速度传输。 修改盒式磁带的前端可将其置于低性能或高性能单元中，从而实现向上和向下的兼容性。 前端的修改可以是手动的或自动的。

    Abstract: A cartridge stores a magnetic recording tape on two reels. Two non-symmetrical molded shells form a hollow chamber retaining the tape and reels and incorporating file protection. Mechanical registration holes through both shells provide distinguishable accesses for photosensing different tape conditions. Indented edges facilitate clamping in a recorder.

    IPC: G11B23/087

    Abstract: A tape-containing cassette facilitates interchange between low-speed recording systems and high-speed or high-performance recording systems. In a low-performance system, the tape is transported wholly within the cassette. The cassette may be removed from a low-performance player and placed in a high-performance player. Then, the tape is partially removed from the cassette for higher speed transport. A front wall opening of the cassette includes a pair of movable front wall end plates. The end plates partially covering the front wall opening facilitate in-the-cassette tape processing. Moving the two end plates to a nonclosure position clears the entire front wall opening to facilitate removing the tape from the cassette for out-of-the-cassette tape processing.
