摘要： A lens includes a front group including a plurality of lens groups; and a rear group that is provided on an image side of the front group and that includes a negative lens and a positive lens. The positive lens has a flat lens surface on its image side, and is tiltable about a spherical center of its object side lens surface that is convex on the object side. When a lens system is inclined, the positive lens is tilted in relation to the optical axis of the lens system based on: a focal length of the overall lens system; an angle of the optical axis of the lens system after being inclined in relation to the optical axis before being inclined; a distance between the image side lens surface of the positive lens and the image plane; and a refractive index of the positive lens.

摘要： A servo pattern writing method of writing a servo pattern for the positioning control of a magnetic head on a magnetic disk comprises changing the rotating speed of the magnetic disk with the magnetic head positioned at one or more proper radial positions with respect to the magnetic disk. The rotating speed of the magnetic disk is changed on the basis of the magnitude of a synchronous vibration synchronous with the rotation of the magnetic disk. Writing current for writing a servo pattern is set according to the change of the rotating speed of the magnetic disk. The STW rotating speed is changed according to the change of the radial position of the magnetic head to reduce the intensity of the vibration that is generated during a servo pattern writing operation to a value meeting a positioning level. The servo track writing operation can be achieved at a low cost.
