  • Patent number: 4467381
    Abstract: A head moving mechanism for a tape deck provides for accurate shifting of a magnetic head from one set of tracks to another by securing the magnetic head to a head carriage member which in turn is attached to the tape deck by two flexures. A solenoid secured to the head carriage member serves to move the magnetic head by means of a linkage mechanism attached to the tape deck.

  • Patent number: 4337909
    Abstract: A tape cassette particularly adapted for use with a dual capstan magnetic tape deck that does not utilize pinch rollers, includes a pair of capstan actuators that respond to a central loading knob which serves to move the tape away from the capstans when the cassette is loaded or unloaded into the tape deck. In addition, the cassette includes a pair of tape guide actuators that respond to the loading knob by rotating and forcing the tape away from the magnetic head and tape guide pins of the tape deck during the loading or unloading operation. This single knob controls both the capstan actuators and the tape guide actuators. The capstans and reels are arranged such that a large angle of wrap, 165.degree. or more, around the capstans is provided in order to effectively drive the tape without the need for pinch rollers.
