ABSTRACT:
The object of the present invention is to provide a test writing method for seeking the optimum write power correctly and in a short time under a high speed recording condition in a test writing method and an information recording device for recording information by forming different marks from the unrecorded part by injecting energy onto the recording medium. To achieve the above object, even number length marks and odd number length marks are separately test written in the 2T strategy to seek the respective optimum write power. Due to the possibility of enhancing the precision of test writing, a good recording ability can be obtained.
