Patent number: 7702993Abstract: A data recording method for an optical disk drive is implemented by the following steps. First, one or more data blocks are encoded and recorded sequentially, and it detects if a buffer under run occurs. If a buffer under run occurs, the recording does not stop immediately until at least the main data of the data block being currently recorded have been recorded completely. Afterwards, it restarts to encode and record from the data block next to the data block where the recording stops. Moreover, the recording also can stops if a servo error is detected, and the data restart to encode and record from the data block where the recording stops or at least one data block preceding the data block where the recording stops.Type: GrantFiled: May 11, 2007Date of Patent: April 20, 2010Assignee: Mediatek Inc.Inventors: Yih-Shin Weng, Hong-Ching Chen

Publication number: 20080080326Abstract: An optical recording method and apparatus for recording data to optical recordable medium are present. The optical recording apparatus at least comprises a PUH module and a verifier. The PUH module is used for recording a first number of data units to the optical recordable medium and reading a third number of data units, which are recorded to the optical recordable medium. The verifier is used for verifying the second number of data units being recorded. After the verifier verifies the second number of the data units, the PUH module follows to an initial position to record a third number of data units without any seeking operation. The PUH module keeps recording and reading and the verifier keep verifying until the plurality of data units being recorded and verified.Type: ApplicationFiled: September 29, 2006Publication date: April 3, 2008Applicant: Media Tek Inc.Inventors: Yu-wei Ling, Yih-shin Weng

Publication number: 20070101211Abstract: A method and device for management of defects in a recording medium such as a DVD disc are disclosed. The present invention utilizes defect processing table to reduce the seek times of a pick-up head in obtaining replacement ECC blocks for defect ECC blocks in a user data area of the disc. The defect processing table is used to indicate a location to access replacement block for a defect block. Since the defect processing table (DPT) stores only the relevant information about the defect block and replacement block rather than the defect block or the replacement block per se, it only needs a very small memory space. The present invention also provides a DPT management unit to manage the contents of the DPT.Type: ApplicationFiled: April 27, 2006Publication date: May 3, 2007Inventors: Chun-ying Chiang, Yih-shin Weng

Patent number: 6778479Abstract: A drive controller is capable of reading information from an optically encoded disk. The drive controller is made to attempt a first read operation from a first area of the optically encoded disk to generate a first data set. If the first read operation is successful, the drive controller then verifies that the first data set conforms to a first data format. A media type descriptor is obtained from the first data set if the first data set conforms to the first data format. A media type descriptor is obtained from a second data set read from a second area of the optically encoded disk if the first data set does not conform to the first data format, or if the first read operation is not successful.Type: GrantFiled: July 11, 2002Date of Patent: August 17, 2004Assignee: Mediatek IncorporationInventor: Yih-Shin Weng
