ABSTRACT:
An apparatus for reading and recording information on a tape record medium has the tape wound and advanced along a helical path on the outer cylindrical surface of the drum. A system for writing and reading information on the tape is positioned entirely on the outside of the drum and is stationary relative to the rotation of the drum and movement of the tape thereon. Tape is supplied to the helical path on the drum by one or more tape reels rotatably mounted within the drum and aligned coaxially with the rotational axis of the drum. The drum and tape thereon are rotated at a high rate relative to the stationary read/write system, and the tape is advanced along the helical path at a relative slow rate. The drum and tape thereon are configured in the form of a cartridge, removeable as a unit from the optical system.
