Abstract
A magnetic tape apparatus intended for consumer use includes at least one digital head with nine digital transmission gaps for reading and/or writing compressed digital information in longitudinal tracks on a magnetic tape. The apparatus also includes electronic circuitry for compressing the digital information prior to writing, and for expanding the digital information after reading. This arrangement enables at least playback of digital audio information at the same frequency used for analog compact cassettes, so that inclusion of an analog head enables playback of analog compact cassettes as well.
