  • Patent number: 8274869
    Abstract: The present invention relates to a method for detecting a blank area of a power calibration area. The method includes the steps of: selecting a recording test area in the power calibration area; writing the recording test area with multiple stages of normal power and detecting power; forming multiple normal blocks and detecting blocks, wherein each of the detecting blocks includes one unit of unrecorded block and one unit of recorded block; and reading information from the unrecorded blocks of the detecting blocks and thus determining whether the unrecorded blocks of the detecting blocks are blank or not. Once all the unrecorded blocks of the detecting blocks are determined to be blank, it represents that the selected recording test area is totally blank.
