摘要： An interleaving method for a high density recording medium and an interleaving circuit therefor. In this circuit, an intrablock interleaver interleaves received data having a predetermined error correction code within an error correction block to output intrablock-interleaved data. An interblock interleaver interleaves the intrablock-interleaved data between the error correction blocks in units of a predetermined number of the error correction blocks to output interblock-interleaved data. Accordingly, the capability of correcting a burst error due to a scratch on a disc is improved while maintaining compatibility with a general DVD format in an error correction format. Also, each row having position information is not interleaved while interblock interleaving is performed, so that a similar access time to the access time in a DVD is achieved. Therefore, high-speed searching is possible.
摘要翻译：一种用于高密度记录介质的交织方法及其交织电路。在该电路中，块内交织器在纠错块内交织具有预定纠错码的接收数据，以输出块内交错数据。帧间交织器以预定数量的纠错块为单位对纠错块之间的块内交织数据进行交织，以输出块间交错数据。因此，改善了由于盘上划痕引起的突发错误的能力，同时保持与纠错格式的一般DVD格式的兼容性。此外，在执行帧间交织的同时，具有位置信息的每一行都不进行交织，从而实现与DVD中的访问时间相似的访问时间。因此，可以进行高速搜索。

摘要： A method and an apparatus are provided for generating an (4,20) RLL modulation code having a decreased detectible window width and an increased recording density ratio. The code's spectrum is concentrated in the low-frequency band, thereby improving the signal-to-noise ratio. In addition, the hardware of an encoder and a decoder can be easily implemented since the modulation code has a fixed codeword length.
