摘要： A hybrid drive is disclosed comprising a head actuated over a disk comprising a plurality of data sectors. The hybrid drive further comprises a non-volatile semiconductor memory (NVSM) comprising a plurality of memory segments. A disk cache is defined comprising a first plurality of the data sectors, and a non-cache area of the disk is defined comprising a second plurality of the data sectors. When a write command is received from a host, data is written to the disk cache, and under certain conditions, the data is copied from the disk cache to the NVSM.

摘要： A hybrid drive is disclosed comprising a head actuated over a disk comprising a plurality of data sectors, and a non-volatile semiconductor memory (NVSM). A read frequency of a first logical block address (LBA) is maintained, and when the read frequency of the first LBA exceeds a threshold and a corresponding PBA is assigned to a data sector of the disk, first data stored in the data sector is copied to a memory segment of the NVSM. When the read frequency of the first LBA exceeds a threshold and the PBA is assigned to a memory segment of the NVSM, first data stored in the memory segment is copied to a data sector of the disk. When a read command is received to read the first LBA, a decision is made to read the first data from one of the NVSM and the disk.

摘要： A force controller wherein lateral, axial and rotational force on a handle (10) are opposed by bending, extension, compression and torsional forces in a tubular flexure element (12) that includes lateral rings (92a . . . 92n) and longitudinal beams (96a . . . 96n-1). A translating plate (23) is controlled in accordance with the torsion and deflection of flexure element (12) to provide optical control signals from code element (56) and read head (64) for three axes of motion. Axial forces on handle (10) cause extension or compression of flexure element (12) which is linked to fin (42). Pivotal movement of fin (42) in response to such extension and compression provides optical control signals from code element (72) and read head (74) for a fourth axis of motion.

摘要： Reservation and allocation of additional space on a hard disk drive for use by an end user is disclosed. A user-accessible area of a hard disk drive is enlarged by determining if a boot engineering extension record is present. If the boot engineering extension record is present, the amount of free media space in the host protected area of the hard disk drive is determined. If media space is available, the unused portion of the host protected area is converted to be user-accessible.

摘要： One aspect of the invention is a method and system for accessing at least one storage element in a processor-based system. The system comprises a memory for storing instruction sequences by which the processor-based system is processed. The memory has at least one storage element. A processor is coupled to the memory, and a storage device is coupled to the processor. Prior to booting an operating system on the processor-based system, the stored instruction sequences cause the processor to write the contents of the at least one storage element to the storage device. Another aspect of the invention relates to a computer system having a user computer in communication with a remote service computer. The remote service computer has access to a database identifying information available to the service computer. A computer implemented method for transferring information to the user computer, comprises: writing the contents of at least one storage element to a storage device on the user computer prior to booting an operating system on the user computer, establishing a communications link between the user computer and the service computer, and presenting at the user computer, information available to the user computer.

摘要： An optical position transducer comprising a coupler responsive to an input light pulse for providing a plurality of light pulses and a movable element movable along a path and having light transmitting regions and light obstructing regions. A first set of light pulse conductors conducts the light pulses, respectively, to a first set of locations closely adjacent the movable element with each of the light pulses being transmitted by the associated light pulse conductor to a different one of such locations. The light pulses are transmitted or obstructed by the movable element to provide a signal representative of the position of the movable element. A second set of light pulse conductors is positioned to conduct the light pulses transmitted by the movable element to a second location. At least some of the light pulses are delayed different lengths of time so that the light pulses from the second set of light pulse conductors can be transmitted as a light pulse train on a single light conductor.
