摘要： The invention provides a single chip implementation of a digital receiver for multicarrier signals that are transmitted by orthogonal frequency division multiplexing. Improved channel estimation and correction circuitry are provided. The receiver has highly accurate sampling rate control and frequency control circuitry. BCH decoding of tps data carriers is achieved with minimal resources with an arrangement that includes a small Galois field multiplier. An improved FFT window synchronization circuit is coupled to the resampling circuit for locating the boundary of the guard interval transmitted with the active frame of the signal. A real-time pipelined FFT processor is operationally associated with the FFT window synchronization circuit and operates with reduced memory requirements.

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.
摘要翻译：磁存储系统包括磁存储介质，磁存储介质包括沉积在磁存储层上或多个磁存储层之间的相对低磁导率软磁材料的保持层。低渗透性保持层可以设置在磁性存储层的上方或下方。在不饱和状态下，保持层用作从存储层上的记录跃迁发出的磁通的分流路径，从而产生保持器中记录的转变的图像场。该分流路径防止从记录的转变发出的信号通量到达头部。为了从磁存储层上记录的转换中读取数据，偏置电流施加到磁头的绕组，产生使保持层的一部分饱和的偏置磁通。一旦饱和，保持器的该部分不再能够分离从由磁头再现传感器表示的区域的记录转变发出的磁通。

摘要： A cover assembly for use with a disk-shaped optical recording medium, having two substantially identical halves, each having an inner surface adapted to provide upon assembly with the medium an air gap adjacent an optical recordable coating on the medium. Each cover half is transparent and has substantially no birefringent characteristics on the region overlying the air gap, thus allowing light to pass unimpeded therethrough. The cover assembly is adapted to be coupled to the central hub of the optical recording medium and to have a raised annulus adjacent thereto to support the assembly and minimize contact with the transparent portion.

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： An optical storage disc has portions for storing pre-recorded or mastered information and portions for storing user writable information, where the mastered portion and the writable portions have different storage capacities or areal data densities. During manufacture, a substrate is formed with a sequence of bumps to represent the mastered information and a series of grooves and lands, where information can later be written on the lands. A phase-change material is deposited over the substrate, the phase-change material changing both physical structure and optical constants when written to, e.g., by a laser.
