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.
Claims8
A method of recording data on external media, the method comprising:
- recording unencoded main data to a memory device;
- reading the recorded main data from the memory device;
- encoding the read main data with an error correction code (ECC);
- scrambling the encoded main data to provide address and parity information;
- recording the address and parity information, but not the encoded main data, to the memory device;
- reading the address and parity information and the unencoded main data from the memory device;
- and
- scrambling the unencoded main data to perform eight-to-fourteen modulation (EFM) on the main data.
