Misreads in decodable indicia by terminals such as bar code scanners (e.g., laser, image sensors) can occur. Solutions can include increasing redundancy or screening out erroneous data. Embodiments of screening error reduction circuits, terminals, and / or methods for processing decodable indicia data are provided.

An EIR terminal containing an image capture device configured to scan an image. The EIR terminal includes a lighting and exposure mechanism. The EIR terminal also includes a camera sensor interface with a stat FIFO. The stat FIFO is configured to receive data from the image capture device. When the stat FIFO, during image scanning, receives a pre-determined amount of image data, it fires an interrupt, which times the lighting and exposure mechanism in the EIR terminal.

A system that allows consumers to manage content and create audio / video presentations in a small portable media device, and to share media files with other users of small portable media devices, without requiring access to a computer.

Audio data are played back by a personal computer, a relationship with a playback process is recognized easily. Displays showing the contents of play lists are arranged and displayed so that the contents become continuous in sequence in a playback sequence from content that is currently being played back from a display of an operation element that causes an image of a playback process to appear or from a display showing the content which is currently being played back. When the playback of one piece of content of one play list from among a plurality of play lists is terminated and one piece of content of an other play list is played back, at least the content that is currently being played back and content to be subsequently played back are displayed so that the contents can be distinguished.

Improved techniques for modifying a playback rate of an audio item (e.g., an audio stream) are disclosed. As a result, the audio item can be played back faster or slower than normal. The improved techniques are resource efficient and well suited for audio items containing speech. The resource efficiency of the improved techniques make them well suited for use with portable media devices, such as portable media players.

An audio signal receiving apparatus includes a sound source information receiving portion to receive sound source information containing sound source type information indicating a sound source type of the audio signal being transmitted through channels and externally connected equipment playback sound source information indicating a sound source type of the audio signal being played back by the externally connected equipment from externally connected equipment, an audio signal receiving portion to receive the audio signal from the externally connected equipment, and a playbackable sound source setting portion to determine and set a sound source type of the audio signal that can played back to a playbackable sound source based on the sound source information. The playbackable sound source setting portion sets a sound source type of the audio signal being played back by the externally connected equipment to the playbackable sound source as an externally connected equipment playback sound source.

Information processing equipment is so constructed that the power consumption of a disk drive for hard disks, optical disks, or the like can be reliably and sufficiently reduced. The host CPU (120) of an information processing unit (100) forms a command for changing the power consumption mode of a HDD (200) based on the state of control on the HDD (200). The host CPU supplies the command to the HDD (200) through a media controller (106). When the HDD (200) accepts the command, it changes its power consumption mode according to the instruction from the information processing unit. Thus, the information processing unit can control the power consumption mode of the HDD (200) based on the state of control on the HDD (200).

A disk drive is disclosed for optimizing write current settings relative to drive operating characteristics and an ambient temperature reading. Test data is written to and read from the disk using different write current settings to generate a plurality of corresponding quality metrics. The quality metrics are evaluated to generate an optimized write current setting for the ambient temperature reading. In one embodiment, the first write current setting is selected relative to a previously optimized write current setting that corresponds to the ambient temperature reading. This embodiment expedites the optimization process by testing write current settings surrounding a previous write current setting rather than testing the entire range of write current settings.

A disk drive is disclosed comprising a disk, a buffer memory, and control circuitry operable to receive a write command from a host, wherein the write command comprises write data and a write data address. Write EDC data is generated in response to the write data and the write data address, wherein the write data and the write EDC data are stored in the buffer memory. The write data is read from the buffer memory, and write check data is generated in response to the write data and the write data address. The write EDC data is read from the buffer memory and compared to the write check data to detect a write error. If the write error is not detected, the write data is written to the disk without writing the write EDC data to the disk.

To effectively suppress a signal in a low frequency region in which the medium noise and the signal distortion are concentrated, and in order to effectively utilize a detected component of the reproduced signal in the low frequency region, a target of partial response equalization to the perpendicularly recorded / reproduced signal is set so that the low-frequency component around the direct current is suppressed to a regulated quantity for both the effective suppression and the effective utilization. Accordingly, a maximum-likelihood decoding process is carried out through the target of partial response equalization. Reliability of data detection is made higher and a signal-to-noise ratio is improved, so that the noise from the recording medium can be reduced more and it is possible to provide a high-density magnetic recording / reproducing apparatus.
