The object of the present invention is to provide an optical recording/reproducing method and apparatus that accurately record data blocks onto an optical disk in a seamless formation while effectively reducing the deterioration of recording properties of the disk. The recording properties of the disk may deteriorate when data is repeatedly written to a same data block of the disk. In the optical recording/reproducing method and apparatus of the invention, a read clock signal is generated in response to recorded data on an optical storage medium. A write clock signal is generated in response to a position information carrying signal detected from the storage medium. A phase difference between the read clock signal and the write clock signal is detected when writing data blocks to the storage medium in a seamless formation. It is determined whether a phase of the write clock signal is delayed or advanced based on the phase difference. In the optical recording/reproducing method and apparatus, a control signal is produced to adjust a phase of the position information carrying signal.
