摘要：
There are provided an optical disk, a magneto-optical disk, a disk apparatus therefor, and a data recording method which can provide improved recording/reproducing characteristics and record durability without linear velocity dependency even if the data access speed is increased by increasing the channel clock frequency. In a disk device for recording data on an optical disk by using a phase change recording scheme, erasing means for erasing data on the optical disk, and recording means for recording other data on the optical disk after the data is erased are provided.
