Abstract
In a method for recording information on an information recording medium having a data recording area for storing user data and a test area used for test recording by a recording apparatus, it is detected whether the test area is unusable when executing the test recording. The test recording is executed in the test area when the test area is detected not to be unusable, or executed in the data recording area when detected to be unusable. Management information relating to the test recording executed in the data recording area is recorded in a predetermined area. Hence, it is possible to eliminate a limit of number of times of test recording which depends on the size of the test recording area.
