Abstract
A device that records and reproduces data using a tape driver and a tape guide drum with an angled rotary magnetic head for forming helical slant tracks for high density recording provides reverse data reproduction and synchronization, regardless of the helical-scanning system used for recording and reproduction, and accommodates error correction codes, to rapidly and accurately reproduce data at various speeds, formats, and error correction codes. The tape guide drum can rotate in both forward and reverse, so that access time is minimized because the tape needs no rewinding prior to playback. The capabilities of reverse direction playback, of handling data other than video data, and of reproducing data at arbitrary speeds provide flexibility for many applications, including a satellite's requirements for rapid, variable-speed playback and transmission of high-density, non-video data.
