Claim:
A method of inspecting a rotation recording apparatus having a rotary recording medium storing positional information recorded thereon and having concentric tracks formed thereon, a head used for reading/writing said positional information from/on said recording medium, and a device used for controlling the relative position of said head with respect to said recording medium, the method comprising the steps of: controlling said head so as to be positioned at a boundary between an outer periphery portion of said track at the outermost periphery or said track and an adjacent track; recording test pattern data in said outer periphery portion or at said boundary; a first decision step of deciding whether or not said test pattern data is written normally; marking two tracks adjacent to said outermost periphery track or said boundary as defective tracks when the decision in said first decision step is yes; controlling said head so as to be positioned in the center of said track; recording test pattern data in said center; a second decision step of deciding whether or not said test pattern data is written normally; and recording said track as a defective track when the decision in said second decision step is yes.
