Abstract
A vault cartridge having a data storage means for the storage of data therein. The cartridge has a size and a shape which is adapted for insertion within a vault receptacle coupled to a host system. The vault receptacle has a primary portion of a magnetic power coupling means made of a primary core and a primary winding operatively coupled to the core. The vault cartridge further comprises a secondary portion of the core having a secondary winding operatively coupled thereto. The portions of the core within both the cartridge and the receptacle are disposed such that when the cartridge is inserted within the receptacle the two portions of the core are magnetically coupled one to the other. A source of excitation energy applied to the primary winding is magnetically coupled through the core and into the secondary winding of the cartridge. Power conversion means is provided within the cartridge for deriving operating power from the secondary winding. The primary winding may also have a current sensing means coupled thereto whereby the host system is enabled to determine the coupling state of the cartridge.
