Abstract:
1. An optical disc apparatus comprising: an optical disc drive for recording on and/or playing back an optical disc; a storage part for storing information; a save control part for accumulating and saving error information in the storage part, in a case in which an error has been generated in the optical disc drive, the error information including information for at least one of any of the following in accordance with a generated error: BCA Movement Error Information for indicating an error in a case in which movement is not possible when an attempt is made to move an optical pickup to a BCA (burst cutting area) provided on the optical disc; No Disc Error Information for indicating an error in a case in which it was recognized that a disc is not present; PFI Error Information for indicating an error in a case in which disc-type information recorded in a PFI (physical format information) region provided on the optical disc was read, and the disc-type information thus read expressed a disc type that is incompatible with the optical disc apparatus; Disc Determination Error Information for indicating an error in a case in which the determined disc type is not the same as the disc-type information included in the disc information that was recorded on the optical disc; Traverse Start Position Error Information for indicating an error produced when an attempt is made to move the optical pickup to a predetermined start position; Disc Eccentricity Error Information for indicating an error in a case in which eccentricity of the optical disc has been detected; Disc Flaw Detection Adjustment Error Information for indicating an error in a case in which there was a failure to adjust for detection of a flaw on the optical disc; Offset Adjustment Error Information for indicating an error in a case in which there was a failure to adjust the offset; Temperature/Focusing Balance Adjustment Error Information for indicating an error in a case in which there was a failure to adjust the focusing balance that corresponds to the temperature surrounding the optical pickup; Disc Weight Abnormality Error Information for indicating an error in a case in which an abnormality in the weight of the optical disc has been detected; Track Meandering Error Information for indicating an error in a case in which it has been detected that a track on the optical disc is meandering; Read Signal Adjustment Error Information for indicating an error in a case in which an abnormality related to the adjustment of an RF signal read by the optical pickup has been detected; Write Strategy Abnormality Error Information for indicating an error in a case in which an abnormality relating to the write strategy implemented by an LD (laser diode) has been detected; Task OS Error Information for indicating an error relating to an OS that manages the tasks of a front-end microcomputer; Focusing Script Error Information for indicating a script error in a program that controls the focusing operation; Tracking Script Error Information for indicating a script error in a program that controls the tracking operation; Motor Script Error Information for indicating a script error in a program that controls a motor; LD Script Error Information for indicating a script error in a program that controls the LD operation, and comprising a storage control part for causing error information accumulated in the storage part to be stored on a removable medium when a predetermined operation occurs in an operation part.
