摘要： In a data demodulating method and apparatus, and a code arranging method, a multiplexer multiplexes an input data stream divided by a predetermined length into a plurality of types of pseudo random data streams using multiplexed information of predetermined bits by applying a predetermined multiplexing method to each of the pseudo random data streams. An encoder RLL-modulates the plurality of types of pseudo random data streams to create a modulated code stream including a minimum of DC components. The multiplexer generates the random data streams by inconsecutively scrambling the input data stream using the multiplexed information. The encoder weak DC-free RLL-modulates each of the multiplexed data streams without using a DC control sub code conversion table to which additional bits are added and provides a code stream including a minimum of DC components among multiplexed, RLL-modulated code streams.

摘要： In order to protect copyrighted data on a disk, a method and apparatus for generating a burst cutting area (BCA) on a disk to prevent unauthorized copy, and an information storage medium having a BCA are provided. The information storage medium comprises: a user data recording area; and a burst cutting area (BCA) on which control information is modulated by using on-off keying (OOK) modulation and recorded. According to the method and apparatus, channel bits after BCA data modulation are generated by inserting a start pattern to data bits before modulation such that a separate modulation table is not needed. Accordingly, the recording density in the BCA increases and by using the start pattern, a sync pattern distinguishable from data is generated and can be used as a signal for a phase locked loop (PLL) when data is restored.

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.
