  • Annotazioni
  • The Magnofilm Tape Deck, Model TM-1 was developed to provide a high quality tape recording and playback mechanism at a popular price.

    It was accomplished by utilizing as a driving medium the power from a gramophone turntable, which provides, in better quality types, the very desirable features of constant speed and high kinetic energy. The heavy flywheel action of a turntable makes it ideally suited for this purpose.

    The Magnofilm Tape Deck comprises a cast chassis of aluminium alloy which accommodates supply and take-up reel spindles, power coupling, capstan, high impedance record-replay heads and tape guide rollers.

    The unit is suspended at three points, two of which are provided by adjustable rear mounting posts, the third being formed by a high traction synthetic rubber power take-off which also carries a stepped pulley. This transmits its rotation to the take-up reel through a moulded plastic belt which is normally located on the smaller step of the pulley to provide forward operating speeds for record or replay.

    An advertisement in Radio & Hobbies, January 1954, page 86, states it was sold complete with an amplifier circuit and a low frequency tape erase unit.
