Abstract: A completely solid state playback and recording system for enormous music and movie collections comprised of read-only and rerecordable memory. The system has no moving parts and delivers a virtually endless and expandable bus to allow a radio or movie broadcaster sized library to be stored, accessed, and programmed for playback at electronic speed. The bus can also be converted to optic fiber, retaining key bus features. Almost limitless numbers of identical memory chips can be utilized without system confusion because the system creates its own address for each memory module on the bus allowing transport and immediate reconnection of sections.
