摘要：
A disc inspecting method includes: forming recording marks on a disc; scanning the recording marks from inside to outside or from outside to inside of the disc by a pickup unit to read a reproduction signal while rotating a spindle to move a slider by each predetermined width; acquiring reproduction data from the reproduction signal in a signal acquiring unit; and determining whether or not the reproduction data is proper in a calculation unit, and optimizing a formation condition of the recording marks when it is determined that the reproduction data is not proper.
