摘要： PROBLEM TO BE SOLVED: To improve processing efficiency by reducing erasure confirmation time for performing erasure confirmation about erased data stored in a storage device. SOLUTION: A data storage means 71, when storing image data taken in through a scanner etc. in an HDD 90 as a storage device, stores data content of the image data as data management information in the HDD 90. When an erasure means 72 erases the processed data and erasure confirmation about the erased data is directed from a CPU 10, a management information reading means 73 reads, from the HDD 90, the data management information corresponding to the data targeted for erasure confirmation. Then, an erasure confirmation means 74 compares the management information read by the management information reading means 72 with a predetermined erasure confirmation criterion, thus decides a method for executing erasure confirmation processing, and performs erasure confirmation processing for the erased data stored in the HDD 90 by the decided execution method.

摘要： PROBLEM TO BE SOLVED: To prevent pitch fluctuation in self-servo write.
SOLUTION: In one embodiment of the present invention, an outer peripheral side area 212 of a magnetic disk 11 is erased by an external magnetic field and an inner peripheral side area 211 is self-erased by a head. Magnetization states of ground before writing patterns are different between the inner peripheral side area and the outer peripheral side area. Thus, different APCs are measured even when a radial pattern 117 with the same pitch is read in the inner peripheral side area and the outer peripheral side area. An SSW in this embodiment uses different reference APCs in the inner peripheral side area and the outer peripheral side area. Thus, the pitch fluctuation is prevented.

摘要： PROBLEM TO BE SOLVED: To improve the reliability of the recorded information in perpendicular magnetic recording.
SOLUTION: A noise level detector 150 is provided in the data channel 130 of a magnetic storage 100 equipped with a perpendicular magnetic recording medium 110 to detect the noise level of the reproduced signals 132 to determine the acceptability. Immediately after writing recording signals 131 on a perpendicular magnetic recording medium 110, the noise level is checked for the reproduced signals 132 read from the writing area. By repeating erasing and rewriting until the noise level becomes lower than the predetermined value, the reliability of the recorded signals 131 is improved for the perpendicular magnetic recording medium 110.
