According to one embodiment, a method includes determining whether a primary velocity is valid and/or in a steady state; averaging a velocity error over a predetermined time period upon determining the primary velocity is valid and/or in a steady state; and calculating a new friction value based on the averaged velocity error.

A microprocessor of a tape drive may identify a pattern associated with data files previously written to tape, predict information about a next data file to be written to the tape based on the pattern, select a tape rate based on the predicted information, and operate the tape drive at the selected tape rate.

Audio is adaptively associated with speakers, depending on the speaker configuration that is present. Each speaker it receives an audio assignment based on its individual spectral characteristics. As more speakers are added, content is adaptively associated with that you speaker, and taken away from the previous.

An apparatus generates outgoing data (OD) to be provided on an optical disk (1) in a burst cutting area (2). The burst cutting area (2) further comprises markings (3) which cause a marking frequency spectrum (MFS) when reading out the burst cutting area (2). The apparatus comprises a channel coder (4) which receives processed data (PD) and supplies the outgoing data (OD) having an outgoing data frequency spectrum (DFS) with suppressed DC-content. The apparatus further comprises a data processing device (5) which generates the processed data (PD) to obtain an outgoing frequency spectrum (DFS) wherein a frequency component causing interference with a low frequent component of the markings (3) is suppressed or not present.

The present disclosure relates to methods, software, and apparatuses for correcting reading and/or writing operations in an optical storage medium. The methods generally include reading a region of an optical storage medium to produce a readback signal, measuring timing offsets for a plurality of the data edges (including one or more non-guide edges), and storing an offset correction for at least one of the plurality of edges based on a measured offset of at least one of the plurality of edges relative to a predetermined offset. The disclosure advantageously enables precise measurement of timing offsets in optical storage media and correction of the measured offsets for timing offsets attributable to edge jitter, timing loop drift, or factors independent of variations in the medium and/or write operation characteristics.

A data recovery device including an analog to digital converter (ADC), a filtering-equalizing unit, a zero crossing detector, a data phase locked loop, a data mapping unit and an estimation unit is provided. The ADC converts a radio frequency signal to a plurality of sampling data points. The sampling data points are converted to a plurality of retiming data points and a clock signal by the filtering-equalizing unit, the zero crossing detector and the data phase locked loop. The data mapping unit selects a plurality of maximum data points and minimum data points from the returning data points, and determines whether to map the maximum data points and the minimum data points to other levels for partially reconstructing the retiming data points. The estimation unit recovers the reconstructed retiming data points to a modulation signal.

摘要:
A record carrier is described comprising a zone with a visually detectable pattern composed of pattern elements arranged along at least one track. The pattern elements comprise a marked zone having an optical property deviating from a background, the marked zones having a width Wm transverse to the track direction and a length Lm along the track direction, wherein at least two or more pattern elements have a marked zone with a mutually different width Wm.In this way, an increased visibility of the visual pattern is achieved. Likewise a method and an apparatus for recording an optical record carrier is included.
摘要:
Compatibility information embedded in an optical medium modifies actions allowed by predetermined non-compatible optical disc drives on the optical medium, such as optical disc drives that may suffer damage if certain actions are performed on the optical medium. For instance, a compatibility engine of the optical disc drive applies compatibility information read from an optical medium to determine restrictions to impose on the use of the optical medium, such as restricting the optical disc drive from writing to the optical medium, reading from the optical medium or performing any operations until an update to the optical disc drive firmware is performed either automatically or by display of a compatibility user interface at an information handling system associated with the optical disc drive. In one embodiment, the compatibility information identifies incompatible optical disc drives and firmware versions by unique identifiers.
