  • Digital data coding and recording apparatus, and method of using the same
    Patent number: 8281225
    Abstract: A data coding apparatus and method for recording digital data on a storage device are provided, where the recording apparatus reduces the number of times that memory is accessed by storing only additional information and parity information when ECC encoded data are temporarily stored in an external memory, and performs data coding without any clock loss by scrambling only a specific field on-the-fly when the data stored in the external memory are read.
    Type: Grant
    Filed: December 1, 2008
    Date of Patent: October 2, 2012
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Dae-Woong Kim, Soo-Wong Lee, Hyun-Woong Lee
  • DIGITAL DATA CODING AND RECORDING APPARATUS, AND METHOD OF USING THE SAME
    Publication number: 20090150749
    Abstract: A method of preparing data for a storage device includes writing unencoded main data to a memory buffer; reading the unencoded main data from the memory buffer; encoding the read main data; scrambling the encoded main data to provide address and parity information; writing the address and parity information, but not the encoded main data, to the memory buffer; reading the address and parity information and the unencoded main data from the memory buffer; and scrambling the unencoded main data.

  • Digital data coding apparatus, DVD recording apparatus, and method of using the same
    Patent number: 7461327
    Abstract: A data coding apparatus and method for recording digital data on a digital versatile disk (DVD) are provided, where the DVD recording apparatus reduces the number of times that memory is accessed by storing only additional information and parity information when ECC encoded data are temporarily stored in an external memory, and performs data coding without any clock loss by scrambling only a specific field on-the-fly when the data stored in the external memory are read.
