Method and apparatus for generating run-length limited code |
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.
