    摘要: A disc type recording medium on which information is recorded by forming disc tracks thereon, a method of forming the disc tracks, and a recording medium for recording a program executing the method. In the above media and method, data access can be rendered in data frame units. The disc type recording medium includes a data frame composed of a plurality of sync frames. The total number of the sync frames is determined according to the length of the innermost circumference of the disc type recording medium. Accordingly, recoding the additional information in such a data frame format prevents a reduction in a rate of detecting the additional information even when the recording medium is miniaturized.

    摘要: A data modulation method to suppress a DC component using parity information of a synchronization codeword, and an apparatus for executing the method. Input data is multiplexed according to multiplexing information, the synchronization codeword including the multiplexing information for a multiplexed data stream is inserted, modulation is performed and plural modulated data streams are output, and a respective one of the modulated data streams having a DC component, which is smallest is selected from among the modulated streams. The synchronization codeword has a bit to control the parity of the codeword, and the input data is multiplexed according to whether a parity of the synchronization codeword is even or is odd. Thus, the DC component included in the modulated codeword stream may be more effectively suppressed without a decrease in a code rate.
