<p><P>PROBLEM TO BE SOLVED: To provide a data erasing device capable of erasing data by simplified operation without fail in order to prevent the data recorded in a magnetic disk device to be discarded from being leaked. <P>SOLUTION: The data erasing device for erasing data of a magnetic disk 5 by a horizontal magnetic field by a magnet comprises a body case having a passage made to let a tray shuttle back and forth, a demagnetization circuit adjacently arranged so that a plurality of permanent magnets arranged along the passage to have polarities so that the magnets are mutually adsorbed, and a tray 21 with a size capable of accommodating a magnetic disk device 1 and reprocicating in the passage. The data erasing device in which a first accommodation groove 63 and a second accommodation groove 31 for accommodating the magnetic disk device 1 are formed in the tray 21, the first accommodation groove 63 and the second accommodation groove 31 are formed to cross each other at an angle of 45°or 90°. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
