    摘要： A playback device (10) (measurement device) in a record playback system (1) including a record player (100) and the playback device (10) measures a frequency characteristic of each of a plurality of input signals which are input from the record player (100) to the playback device (10) when a plurality of test signals for measuring a characteristic of the record playback system (1) are played back by the record player (100), the plurality of test signals being recorded on a phonograph record, the plurality of input signals corresponding to the plurality of test signals recorded; calculates a measurement error between the frequency characteristic of each of the plurality of input signals measured and a predetermined frequency characteristic; selects a frequency characteristic of which the measurement error is smallest from among the frequency characteristics of the plurality of input signals, as a measurement result of the record playback system (1); and outputs the measurement result selected.

    摘要： Drive units for a data medium, e.g. a CD or a DVD, generally comprise a turntable and a clamp. It would be advantageous to provide a drive unit having an improved torque 5 transmission from the rotatable parts of the drive unit to the disc. It would also be desirable to allow a better guiding of the disc into a centered position around the axis of rotation from the supporting surface. To better address one or more of these concerns, an embodiment of the invention provides a drive unit for a data medium, comprising a turntable and a clamp for clamping a data medium onto the turntable, wherein the turntable 10 and the clamp can be moved with respect to each other from an unclamped to a clamped position, and, in the clamped position, the turntable and the clamp comprise a form-fit torque transmission between them.

    摘要： An integrated storage device, for storing a data package received wirelessly from a remote base station, includes a secondary non-volatile storage device, an antenna, a primary non-volatile storage medium, and a processor. The antenna is configured to receive the data package wirelessly from the remote base station. The antenna is also configured to receive electrical energy from the remote base station in order to power the secondary non-volatile storage device, such that, the secondary non-volatile storage device is accessible in order to store the data package. The primary non-volatile storage medium is only accessible when electrically connected to a power supply. The secondary non-volatile storage device and the primary non-volatile storage medium are permanently operationally connected. The processor is configured to copy the data package from the secondary non-volatile storage device to the primary non-volatile storage medium when the primary non-volatile storage medium is electrically connected to the power supply

    摘要： An optical information reader for writing/reading of multi-layer optical disks utilizing light beam from the light source directed to optical carder by the lens and receiving reflected or fluorescent light is described. An optical reader includes the device for the reception of reflected of fluorescent light and the detector of the disk writing/reading layer with the aim to determine a required value of compensation or correction of spherical aberration compare to the calculated one. Optical reader includes also a piezo-ceramic optical element (1, 2, 3, 4) resided in a light beam that is directed from light source to the carder. This piezo-element has a phase difference between central (1, 2) and peripheral (3, 4) zones that depend on sign and value of voltage applied to it. A piezo-ceramic device reduces aberrations by using the phase differences change between its central and peripheral zones as result of current change of record layer thickness.

    摘要： Computer systems may loose data when a failure occurs within a system. To counteract such loss of data a backup system may be employed. Common backup systems make a copy of either of the data on a storage device or the data, which has changed, on a storage device. The process of backing up data may involve storing a relatively large amount of data and so is commonly done infrequently, such as once per day. If a computer's data is backed up only once per day, several hours of data may be lost if a computer system falls. Embodiments of the present invention may be used to prevent this type of data loss by backing up more frequently. In order to back up more frequently less data at a time is backed up. Instead of the data undergoing a wholesale backup infrequently, embodiments of the present invention form a timed log of the storage writes performed by the computer system. The log provides a running picture of activity to the computer storage system. By preserving the log, for example storing it at a remote site through a network connection, the state of the computer can be recreated with any desired granularity, by using the log entries to recreate the state of the data within the computer system at any desired time.

    摘要： A limited-use tape cassette includes a follower arm (420) pivotally secured to the housing at one end (422) while abutting the spooled tape (8) of a cassette reel (6) at a distal end. A use-limiting mechanism is provided by the follower arm (420) or another inter-related arm to control rewinding and/or playback of the tape based on follower arm position and/or positional history. In one embodiment, a second rotatable arm (30) is located in controlled interference with the follower arm so as to cause it to "lock up" after a predetermined number of unfettered play back/rewind cycles have taken place. In other embodiments, the arrangement (Fig. 12) utilizes existing brake teeth of a tape cassette reel to prevent rewinding after a predetermined amount of the video has been viewed.
