摘要： Embodiments of the invention relate to erasing data recorded on a magnetic disk with increased certainty by using an external magnetic field. One embodiment is directed to a method for erasing data recorded on a magnetic disk, which is housed in a magnetic disk drive, by using an external erasure magnetic field generated by an external erasure magnetic field generator. The method comprises the steps of: moving a first magnetic disk drive within an external erasure magnetic field in a moving state appropriate for the type of the first magnetic disk drive, and erasing data recorded on a magnetic disk in the first magnetic disk drive; and moving a second magnetic disk drive, which differs in type from the first magnetic disk drive, within an external erasure magnetic field in a moving state that differs from the moving state of the first magnetic disk drive, and erasing data recorded on a magnetic disk in the second magnetic disk drive.

摘要： Embodiments of the invention prevent a spindle motor from stopping rotation while data on a magnetic disk is being erased by using a permanent magnet. In one embodiment, data in the whole area of the magnetic disk is erased as a consequence of the magnetic disk rotating in the magnetic field of the permanent magnet located so as to face a part of the magnetic disk. A back yoke is located so as to face a base. The back yoke gives a magnetic force to the spindle motor in the opposite direction of the magnetic force of the erasing permanent magnet so that the fluid dynamic bearing spindle motor can retain the rotation as required without stopping rotation.

On a recording plane Rec, provided is a region M1 in which an original image Pic(A) is recorded, a region M2 in which an original image Pic(B) is recorded, and a middle region Mm positioned therebetween. The region Mm is divided into a plurality of strip-like regions f1 to f6. The widths of the strip-like regions f1, f3, and f5 that are odd-numbered when counted from the region M1 are set so as to increase monotonically in this order, while the widths of the even-numbered strip-like regions f2, f4, and f6 are set so as to decrease monotonically in this order.

摘要： A recording plane of a computer-generated hologram that is capable of reconstructing a full-color image and achieving a high resolution is divided by a multiplicity of parallel sections in the horizontal direction to define a multiplicity of areas. Amplitude information and phase information corresponding to different wavelengths which vary periodically in a direction traversing the multiplicity of areas, is recorded in the recording medium. Information about the same portion of the original image is recorded in individual points belonging to the same area, and information about another corresponding portion of the original image is recorded in individual points belonging to another area.

摘要： A method and a device for manufacturing a hologram recording medium that has an arrangement by which different original images are reproduced when observed from different positions. The method includes preparing a plurality of original images, setting a predetermined recording plane, setting a predetermined reference light, setting a plurality of observation regions, computing an interference fringe pattern, and forming the interference fringe pattern on a physical medium. When computing an interference fringe pattern, computations of only the light components of each original image which would reach the respective observation region are performed.
