ABSTRACT:
A pattern buffer apparatus for a dynamic write strategy, which buffers non return to zero (NRZ) data patterns in order to generate a recording pulse in a compact disc system, includes a pattern detector which detects a pattern edge and a pattern from the NRZ data; a write address generating unit which generates a write address indicating a pattern buffer which stores the pattern in response to a write enable signal; the pattern buffer which has a plurality of registers and stores the detected pattern according to the write address; and a read address generating unit which generates a read address in response to a read enable signal, and reads the current pattern stored in the pattern buffer indicated by the read address.
