The optical recording disc (1) includes a start file (19) for executing a predetermined processing upon mounting on the disc drive and a start specification file (18) for specifying automatic execution of the start file (19) which files are attached to the data (20). The start file (19) has a function to execute access processing to an enlarged recording area (15) located at the tail of a recording area (10) prior to execution of predetermined processing.
It is possible to provide a data recording medium discarding method capable of effectively discarding a data recording medium while assuring security of the recorded data and performing recycling. The method includes a step for containing at least one of an optical data recording medium and a magnetic data recording medium containing information to be discarded, in a collection box (95) and sealing the collection box (95) by sealing means (97), a step for transferring the sealed box (95) to a processing location (8), and a data discarding step for destroying and erasing recorded data by subjecting the transferred collection box (95) in the sealed state to an optical data destruction device or a magnetic data erase device.
