    摘要: In one embodiment, a storage device with biometric access includes: a biometric scanner adapted to scan a biological feature of a user to provide a corresponding extracted biometric template; and a storage engine adapted to retrieve an encrypted biometric template from a storage medium and to retrieve a corresponding encrypted content key from the storage medium. The storage engine generates a first key and combines the first key with a media identifier from the storage medium to provide a content key. Using the content key, the storage engine decrypts the retrieved encrypted biometric template. If the extracted biometric template matches the retrieved biometric template, the storage engine grants a user access to content on the storage medium.

    摘要: A magnetic storage system includes a magnetic storage medium comprising a keeper layer of relatively low permeability soft magnetic material deposited upon a magnetic storage layer or between multiple magnetic storage layers. The low permeability keeper layer may be disposed either above or below the magnetic storage layer. In the unsaturated state, the keeper layer acts as a shunt path for flux emanating from recorded transitions on the magnetic storage layer, producing an image field of the recorded transitions in the keeper. This shunt path prevents signal flux emanating from the recorded transitions from reaching the head. To read data from a recorded transition on the magnetic storage layer; a bias current is applied to windings of the head, creating a bias flux which saturates a portion of the keeper layer. Once saturated, this portion of the keeper can no longer shunt flux emanating from the recorded transition, which is the region represented by the head reproduce transducer.

    摘要: The flexible, particulate magnetic storage medium includes a substrate and a magnetic storage layer of hard magnetic particles held within a binder. The flexible, particulate magnetic storage medium also includes a soft magnetic keeper layer. The soft magnetic keeper layer may be established by coating the individual hard magnetic particles of the magnetic storage layer with a layer of soft magnetic material to establish a "keeper layer" around each particle. A break layer of non-magnetic material may be provided between the hard and soft layers. The individual particles are coated by methods such as in situ precipitation. The soft magnetic layer may also be established by providing a separate layer of soft magnetic material within a binder of cross linkable resins. The resulting flexible, particulate magnetic storage medium is a laminate principally comprising a substrate, a first layer of hard magnetic particles within a binder, and a second layer of soft magnetic particles also within a binder. The laminate medium may be produced through extrusion of binder particle mixes through multi aperture slot die extensions. The flexible, particulate magnetic media may be used in tape or flexible disc formats.

    摘要: A modularized information display panel is formed of identical modules which have thin film transistor control elements disposed at display elements which are in an X-Y array upon the module substrate. The display medium driving electrode portion of the thin film circuit which is associated with each display element is non-symmetrically spaced relative to a unit display element, but the display element electrode is symmetrically positioned relative to the center of symmetry of the individual modules which make up the panel. In this way abutted display modules which form the display panel have display element arrays which are symmetrically aligned in the X-Y directions while the interconnecting X-Y buses of the abutted modules are offset.
