摘要： PROBLEM TO BE SOLVED: To provide a carriable data erasing device capable of surely erasing data by a simple operation in order to prevent the leakage of the stored data of a magnetic disk device to be discarded.
SOLUTION: The data erasing device 50 for erasing data recorded on a magnetic disk 5 by using magnetic fields generated from permanent magnets 27 and 28 is provided with a slide tray 20, a main body 30 and a swing tray 40. The slide tray 20 is inserted into/ejected from the main body 30, and the permanent magnets 27 and 28 adjacently arranged to have polarities for mutually attracting N and S poles are attached to the tip side of the slide tray 20. One end of the swing tray 40 is fixed to the upper surface of a main body case 31 by a shaft, and the magnetic disk device 1 is mounted to be swingable on the upper surface of the case 31. The magnetic disk device 1 is swung by a swing tray 40 while the sldie tray 20 is gradually pulled out of the main body 30, and data on the magnetic disk 5 are erased.

摘要： PROBLEM TO BE SOLVED: To shorten an operation time required for precluding the reading of data from a recording medium.
SOLUTION: A command processing part 11a in an information leakage prevention device 1 transmits a format command to an HDD 2. While the HDD 2 is being formatted, a format abnormal state generation part 11b transmits a reset command, or interrupts power supply to the HDD 2 by a power supply part 14 to cause an abend during formatting of the HDD 2, thus precluding the reading of data from the HDD 2.

摘要： PROBLEM TO BE SOLVED: To provide a data erasing apparatus which can surely erase data with a simple operation regardless of a recording system to prevent leakage of stored data of a magnetic disk apparatus to be discarded. SOLUTION: The data erasing apparatus 60 erasing data of a magnetic disk 5 by a magnetic field in a horizontal direction and a vertical direction by a magnet is constituted of a main body case 62 having a path 68 continued to an opening part 67 provided at one side plane, a first magnetic field generating source arranged adjacently so that polarity of three permanent magnets provided at one plane of this path 68 attract one another, a second magnetic field generating source constituted of three permanent magnets opposing to the first magnetic field generating source across the path 68, and a tray 61 having size in which a magnetic recording medium 1 is housed and it can be reciprocated in the path 68. The polarity of only the permanent magnet positioned at one side of end parts of the second magnetic field generating source is made the same direction as the opposing permanent magnet, polarities of other two permanent magnet are made an inverse direction to the opposing permanent magnet.
