HEAD SUPPORT AND POSITIONING ASSEMBLY FOR RECORD/PLAYBACK DEVICE ABSTRACT OF THE DISCLOSURE Apparatus is provided for supporting and positioning a record/playback transducer with respect to a record medium in a record and/or playback device. The transducer is supported on a mounting plate which is guided for bi-directional sliding movement to position the transducer in engagement, disengagement and partial engagement with the record medium in response to motive power provided by a selectively energizable motor. Energizing power is supplied to the motor in response to the actuation of a respective function control switch, and the motor remains energized until the mounting plate moves the transducer into the appropriate position by which the selected function may be carried out. In one embodiment, the motor rotates a cam whose cam surface is in contact with a portion of the mounting plate. The position of the plate and, thus, the transducer, is sensed as a function of the angular position of the cam.
