  • Optical disc recording and reproducing apparatus permitting recording tests using external buffer memory and method of driving the apparatus
    Patent number: 7372787
    Abstract: An optical disc recording and reproducing apparatus permitting a recording test using an external memory, and a method of driving the apparatus is provided. The optical disc recording and reproducing apparatus reads and bypasses test data to be recorded, which is stored in a buffer memory in a compact disc-digital audio (CD-DA) format or a data format similar to the CD-DA format. The bypassed data is directly converted into serial data by a synchronizer without being encoded, and is then used in a write strategy for a write strategy unit.
