发明名称 Method for recording information on an erasable optical recording medium
摘要 There is provided an optical information recording method which can manage a number of recordings which can be performed on each of several partitions in a test area. The recording method uses an erasable recording medium on which information is recordable a plurality of times in the same area by a laser beam. The erasable recording medium includes a data area in which the information is recorded and a test area divided into a plurality of partitions each of which is provided for testing a recording power of the laser beam. In the method, the laser beam is projected onto one of the partitions so as to perform a test recording. The recording power of the laser beam is calibrated so as to adjust the recording power to an appropriate level before recording the information in the data area of the erasable recording medium. Then, the number of test recordings is recorded in a predetermined area of the erasable recording medium. Accordingly, the format of the erasable recording medium is compatible with a conventional optical recording medium such as a recordable compact disc (CD-R).
