  • Patent number: 7248557
    Abstract: For the purpose of providing sector-address information on optical disks, a robust header is realized by utilizing a very simple encoding method that allows asynchronous reading. In order to provide robustness and reliability, the header uses a biphase data format to encode addressing information. The embossed header is further configured with redundant address-fields in a checkerboard pattern between adjacent tracks, in order to provide robustness for media-contamination. Each address-field starts with a unique address-mark and ends with parity-check information to provide reliable error-detection. The entire header can be decoded without the need for a slice-level, thus making it very tolerant to amplitude-variations and DC-offset variations. By combining these characteristics, a header is achieved which is reliable and inherently resistant to failures in providing sector-address information on optical disks.

  • Publication number: 20070097825
    Abstract: A waveform reconstructor is utilized in the read channel of an optical storage system in order to produce a high speed and reliable data output. Generally speaking, the waveform reconstructor provides readout signals from the optical storage media without utilizing a phase locked loop. In order to accomplish this, readout signals are first converted to digital signals, then provided to a digital equalizer for further signal conditioning. This equalizer use provides several advantages not available when PLL designs are utilized. Readout samples are then processed to determine a phase error, as compared with an ideally sampled signal. Once determined, this phase error allows for the reconstruction of the waveform, to create an output which is consistent with one which would have been sampled at precisely the correct time. The waveform reconstructor manages the calculated samples to determine whether actual asynchronous sampling is inconsistent with the anticipated samples.

  • Patent number: 7200771
    Abstract: A method is provided that minimizes the seek time necessary for relocating bad sectors found during data processing. During standard data processing in the prime disk area, identified bad sectors are saved in memory until after all of the data processing has been completed. The bad sectors are then relocated from memory in a batch process, thereby requiring only a single seek command to the defect management area. This procedure reduces the time penalty in the number of relocations to a near constant time and avoids a linear time penalty.

  • Publication number: 20070047395
    Abstract: Data protection and security is provided by incorporating a data shredding operation which renders data previously stored on storage media unrecoverable. In the shredding operation of the present invention, certain overhead portions of a data storage sector remain unchanged, while the data area is overwritten with a predetermined pattern. By maintaining the overhead portions of the sectors (addressing, verify and protect, error correction codes, etc.) the sectors can be easily identified as being previously shredded, thus not providing a source of possible confusion to the data storage device. Further, the data becomes unrecoverable as it has been overwritten by the predetermined pattern, which thus eliminates all previously existing transitions which contained the encoded data.

  • Publication number: 20060209663
    Abstract: In order to help maximize the capacity of an optical storage device, and increase the efficiency of addressing, a unique addressing scheme is utilized to provide addressing for an optical storage disk. Importantly, this scheme is compatible with multilayer disks and helps to minimize the potential for errors. In the addressing scheme of the present invention, the storage media is provided with a wobbled groove, which includes addressing information for the media. More specifically, the surface of the media is divided into predetermined sections, or portions, each portion having a selected number of wobble periods. Within these wobble periods, the amplitude of one single wobble period is either reduced or eliminated. The location of this reduced or eliminated wobble signal can then be determined by the readout system of the present invention and utilized to provide addressing information.

  • Patent number: 6961291
    Abstract: An auto-focus system for a DVD reader or other optical access unit which reads and/or writes information from/to at least two information layers on an optical storage medium such as a DVD or DVR. The auto-focus system includes an astigmatic lens. A confocal aperture is placed at the first focal line image generated by the astigmatic lens from light rays reflected from the addressed information layer. The placement of the confocal aperture allows extraneous out-of-focus light rays reflected from non-addressed information layers to be blocked from reaching the photo detector array which then creates a focus error signal (FES). The FES drives a servo assembly connected to an access head of the optical access unit, bringing the access head into focus. In some embodiments, the confocal aperture is “bow-tie” shaped, allowing for simplified assembly and easing in-plane rotational alignment.

  • Patent number: 6891868
    Abstract: In order to provide a low noise laser beam, a noise reducing feedback network is provided which creates a noise reducing signal and provides that signal to the laser itself. In order to produce the noise reducing signal, the operation of the laser is monitored and the feedback signal is a direct result of this monitoring. Monitoring is accomplished by a fast-forward sense detector, which receives a portion of the laser beam from the operating laser. The output from this fast-forward sense detector is provided to an amplifier which inverts and amplifies the signal. A noise reduction feedback network then receives the amplified signal, appropriately filters this signal, and provides it to the laser itself so as to reduce noise in the laser-beam for the frequency band of importance for reading the recorded data from the optical medium.

  • Publication number: 20040017749
    Abstract: In order to minimize potential damage to a rewritable storage media, and to consequently extend the life of the media, the laser power is carefully controlled in order to avoide sharp power transitions. Rather than simply turning the laser power on to its full power level, the power utilized during writing dedicated sections of data sectors is transitioned from 0 to its full power level over a desired period of time. In this way, the thermal shock caused by repeated rewriting in these areas can be minimized, thus extending the life of the rewritable media.

  • Patent number: 6487146
    Abstract: Writing predetermined data pattern to an allocated segment of a disk drive and appropriately reading that one data pattern while varying the read focus characteristics provides for efficient and effective read focus optimization in an optical disk drive. In order to produce helpful data, the read focus offset is varied while reading the different segments of the data pattern, thus producing read out signals with different peak to peak amplitudes. This is compared to data which is obtained by reading the same data pattern while the offset is held constant. Optimization of the read focus offset is carried out and made possible by appropriate analysis of the waveforms produced when reading the predetermined data pattern in these two reading passes. By appropriately tracking the results of the various read focus offsets, an optimum read focus offset can be easily determined.

  • Patent number: 6467014
    Abstract: Automated address mapping is achieved by a system and methodology which automatically reacts to changes in the disk configuration. Prior to utilizing the disk, disk configuration information is provided by the user resulting in a stored configuration table. This configuration table is then used to compute an address translation structure which can be later used to perform actual address mapping operations. Utilizing this address translation structure, in combination with appropriate formulas, address mapping from a logical block address, provided by the host computer, to a surface-track-sector address (STSA) is easily accomplished. By having the actual address translations dependent upon the configuration table, the system and method automatically reacts to changes in the disk configuration.
