    • A magnetic tape recording and reproducing apparatus uses a cassette (2) having a pressure roller (4) near one corner with an aperture in one adjacent edge for a drive roller (12) to engage the tape (1) and an aperture in the other adjacent edge for the tape to engage a transducing head (10). The drive roller (12) and head (10) are fixed in position and a spring (14) presses the cassette (2) towards the drive roller (12), the pressure on the pressure roller (4) also serving to retain the cassette (2) and locate it in against fixed stops (22). The head (10) has projections (25, 26) for aligning the tape (1) and determining the position of the cassette (2). The head position is referenced to the casing by standing on a surface (11) of the casing and being held in place by resilient arms secured (31) to the casing. The head (10) is connected to a read-write circuit using a push-pull amplifier powered by two current sources. Any one of a plurality of such apparatus can be selected using a chain of D-type flip-flops (one per apparatus) and applying a number of clock pulses corresponding the apparatus to be selected.
    • 磁带记录和再现装置使用在一个角附近具有加压辊(4)的盒(2),其中一个相邻边缘的孔用于驱动辊(12)以接合带(1)和另一个孔 用于带的相邻边缘接合换能头(10)。 驱动辊(12)和头部(10)固定就位,并且弹簧(14)朝向驱动辊(12)推压盒(2),压力辊(4)上的压力也用于保持盒 (2)并将其定位在固定挡块(22)上。 头部(10)具有用于对准带(1)并确定盒(2)的位置的突起(25,26)。 头部位置通过站立在壳体的表面(11)上并且通过固定(31)到壳体的弹性臂保持就位而参考壳体。 头(10)使用由两个电流源供电的推挽放大器连接到读写电路。 可以使用D型触发器链(每个装置一个)来选择多个这样的装置中的任何一个,并且应用与要选择的装置相对应的多个时钟脉冲。
