Reverse error correction coding with run length limited constraint
First Claim
Patent Images
1. A method for communicating data comprising:
- RLL encoding the data in accordance with a run length limited (RLL) code; and
placing a seed in the RLL encoded data, the seed selected to provide error correction code (ECC) parity in accordance with an RLL constraint to thereby generate channel data.

Abstract
A method and apparatus for communicating data is provided. The data is encoded in accordance with a run length limited (RLL) code. A seed is appended to the RLL encoded data. The seed can be used to alter the error correction code (ECC) parity to meet an RLL constraint.
