记录装置和方法、光学记录介质、再现装置和再现方法
摘要：
本发明的目的是减少因缺乏测试区域而造成阻止数据记录的可能性。对于光学记录介质的多个记录层中的每个记录层，设定测试区域，对测试区域执行试用写入以控制激光功率，并且表示所设定的测试区域的实际位置的信息被记录。通过再现记录在包括多个记录层的光学记录介质中的信息，以及记录表示所设定的测试区域的实际位置的信息，来获取表示测试区域的实际位置的信息，其中每个记录层设定有测试区域，对测试区域执行试用写入以控制激光功率。
摘要（英）：

Provided is a technique that reduces the possibility that data will not be recorded due to a shortage of test areas. A test area, in which test writing for laser power control is performed, is set in each recording layer of an optical recording medium having a plurality of recording layers, and information indicating a position of the set test area is recorded on the optical recording medium. Furthermore, recorded information of an optical recording medium is reproduced, the optical recording medium including a plurality of recording layers and in which a test area, in which test writing for laser power control is performed, is set in each of the recording layers and information indicating a position of the set test area is recorded; and the information indicating the position of the test area is acquired.
