Abstract
The invention provides a two-dimensional run-length limited (RLL) (1,3) code method and apparatus. The codec comprises an encoder and a decoder comprising a data buffer and grouping module, a two-dimensional code word generating module, a two-dimensional word unit page constructing module, a two-dimensional code word write array module, and a protection word stuffing module. The five modules are sequentially connected, and send output through the protection word stuffing module to a two-dimensional data recording device. The decoder comprises a two-dimensional data buffer module, a two-dimensional word unit page constructing module, a one-dimensional data word decoding module, and a one-dimensional data stream assembly module. The five modules are sequentially connected, and send output through the one-dimensional data stream assembly module. The encoding/decoding method and apparatus can solve problems that any binary two-dimensional data array composed of 0's and 1's satisfies two-dimensional (1, 3) RLL constraints in both horizontal and vertical directions.
