Abstract
The solid state memory device consists of a circuit board based system which is mounted in a 3480 type magnetic tape cartridge form factor housing to make this media physically compatible with the 3480 type magnetic tape cartridges. The interconnection of the solid state memory device with the read/write device is by an optical connections which transfer data between the solid state memory device and the associated read/write device. A plurality of batteries in the solid state memory device provide power for the memory retention capability required of the volatile solid state memory devices. The batteries are recharged by the use of a pair of power rails that are incorporated into the exterior housing of the 3480 form factor cartridge. Thus, the associated read/write device applies power to the solid state memory via these power rails when the 3480 form factor cartridge is placed in the associated read/write device. Likewise, an associated manual or automated cartridge storage system supplies power when the cartridge is offline, in storage.
