Title:
データ変調装置及びデータ復調装置
Document Type and Number:
Japanese Patent JP4559112
Kind Code:
B2
Abstract:
The method involves dividing an input data stream by a preset length and multiplexing the stream using the multiplexed information based on a preset multiplexing method to provide a multiplexed data stream. The multiplexed stream is weak DC-free run length limited-(RLL) modulated without a separate DC control code conversion table. A code stream with a minimum DC component is provided. Independent claims are also included for the following: (a) a data demodulating method (b) a method of arranging m-bit source data into n-bit (c) an apparatus for modulating m-bit source data into n-bit (d) a data demodulating apparatus (e) a computer-readable medium with instructions for performing operations of a data modulating method.
