Abstract: PURPOSE: A method for detecting block boundary violation and an appropriate device therefor are provided to discriminate normal recording, by comparing phases of a start position of an encoding block and a boundary position of an ECC(Error Correction Code) block on a disk, so as to normally record data. CONSTITUTION: An LDD/ADIP(Land Pre-Pit/ADress In Pre-groove) decoder(30) generates a block boundary signal by receiving an LPP signal or an ADIP signal. Window generators(31-33) respectively generate a first window signal for detecting an advancing state, a second window signal for detecting an entity within a tolerance field, and a third window signal for detecting a delayed state. A DVD(Digital Versatile Disk) encoder(34) applies an ECC for received data to generate an encoding block, and outputs the generated encoding block with an encoding block synchronizing signal. AND gates(35-37) respectively compare the encoder block synchronizing signal provided from the DVD encoder with the first, second and third window signals generated in the window generators, and output compared results as first, second and third interrupt signals. And a recording unit(38) and a micro-processor(39) perform recording or suspend recording, according to the states of the first to third interrupt signals.
