摘要： Embodiments in accordance with the present invention control pitch variations that are not observed in self servo write (SSW). According to one embodiment of the present invention, an outer radius side area of a magnetic disk is erased using an external magnetic field, and an inner radius side area is subjected to self erase using a head. The magnetization state in the base of the inner radius side area is different from that of the outer radius side area before pattern writing. Therefore, in the inner radius side area and the outer radius side area, even if a radial pattern of the same pitch is read, the different APCs are measured. With SSW of this embodiment, a reference APC used in the inner radius side area is different from that used in the outer radius side area. In this manner, the pitch variation is prevented.

摘要： The invention relates to a method for writing servo patterns on a data recording disk of a disk drive device. A read/write head is stopped at a reference position on the data recording disk, then the read/write head is moved along a radial direction of the data recording disk from the reference position, then a determination is made as to whether the data recording disk has a sufficient width along the radial direction to write a predetermined number of servo tracks, or not, then the servo patterns are written on the servo tracks if the data recording a disk has the sufficient width.

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.

摘要： A storage device of a report producing terminal stores an importance table. The importance table stores grades of importance of respective items of accessory information on medical images. Prior to displaying a medical image on a screen, an area defining section extracts a main subject display area of the medical image, and defines an accessory information display area outside the main subject display area. A display style defining section calculates a necessary display area for each individual item of the accessory information, and discriminates between those items which fit in the accessory information display area and those which do not. The display style defining section decides not to display the items which do not fit in the accessory information display area, or decides to display them in a transparent style, in a scrolling style, in a switching style or with a small font.
