HARD DISK DUPLICATION DEVICE AND HARD DISK USED IN DUPLICATION

摘要

PURPOSE: A hard disk duplication device and a hard disk used for duplication are provided to restore data recorded in a physically damaged hard disk by duplicating data of undamaged portion of the disk into another hard disk though a magnetic stray field. CONSTITUTION: A hard disk duplication device comprises a first hard disk part(112), a second hard disk part(113), a motion control part(114), and an auxiliary magnetic field generating unit(111). A first hard disk is inserted into the first hard disk part. A second hard disk is inserted into the second hard disk part. In case the first hard disk is inserted into the first hard disk part and the second hard disk is inserted into the second hard disk part, the first hard disk part is moved close to the second hard disk part by the motion control part. The auxiliary magnetic field generating unit generates a magnetic field on the first hard disk.
