    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).

    摘要： An optical recording apparatus records information on a rewritable recording medium having a pre-recorded address guide by an external link method without performing complex calculations. Data is recorded on the rewritable optical recording medium on an individual block basis along the pre-recorded address guide, the block including a predetermined number of sectors each of which has a consecutively numbered sector address. A link part having a predetermined fixed length is recorded between adjacent blocks. The link part lacks an address so that the sector address shifts from an address indicated by the pre-recorded address guide by the length of said link part.

    摘要： An optical disc recording apparatus which can record information, which is provided in a packet having a fixed length, on an optical disc on an individual user data block by using the fixed packet write method. A plurality of tracks having a plurality of packets are formed on a recording area of the optical disc. Each of the packets has the same number of user data blocks. Information is recorded at once on an individual packet basis. A buffer stores new recording information to be recorded on the optical disc. A controller controls a recording operation of the new recording information on the optical disc so that, when a recording area of the new recording information is totally included in a previously recorded packet, previously recorded information recorded in the previously recorded packet is read and stored in the buffer. The previously recorded information stored in the buffer is overwritten by the new recording information. Then, the new recording information in the buffer is recorded in the previously recorded packet.
