摘要： A recording disk drive includes a shroud wall spaced from a peripheral end of the recording disk by a gap equal to or smaller than 0.5 mm. A rectification groove is formed in the shroud wall at a position adjacent an area opposed to the peripheral end of the recording disk. Reduction in gap between the peripheral end of the recording disk and the shroud wall serves to reduce the amplitude of the flutter to be induced in the rotating recording disk. Moreover, as the gap gets smaller, the flutter reduces at a higher rate in response to increase of the depth of the rectification groove. Specifically, if the gap between the peripheral end of the recording disk and the shroud wall is set equal to or smaller than 0.5 mm, the groove can be made shallower so as to still efficiently suppress the flutter of the rotating recording disk.

摘要： A thermal component is mounted on the front surface of an isolator sheet within a first specific area. A thermally-conductive material is located on the back surface of the isolator sheet on the back of the first specific area. An electrically-conductive material is located on the front surface of the isolator sheet within a second specific area. A thermally-insulating material is located on the back surface of the isolator sheet on the back of the second specific area. The flexible printed circuit board unit of this type allows heat of the thermal component to efficiently radiate from the thermally-conductive material. An increase in temperature can be suppressed in the thermal component. Heat can reliably stay in the electrically-conductive material when a solder material is applied to the surface of the electrically-conductive material. The solder material is allowed to reliably fuse.

摘要： A disk drive includes a casing for enclosing at least a disk and a head. Rectification walls are disposed at corners of the casing. The walls serve to rectify an air stream generated by rotation of the disk at the periphery of the rotating disk. A bypass is defined between the side wall of the casing and at least one rectification wall. A filter is disposed in the bypass for catching dust in the air stream. A parameter d/L, where d is the width of an entrance of the bypass and L is the length of the comer along the periphery of the disk, is determined so that vibration of the rotating disk is equal to or less than an admissible value estimated from a tracking error margin. The tracking error margin is estimated from a track pitch on the disk. Reliable positioning of the head with respect to the disk can be achieved with the present invention.

摘要： For a magnetic disk apparatus for reading and writing information to a magnetic disk in the present invention, the recessed portion of the cover of the magnetic disk apparatus has a two-level structure; the space between the inner surface of the recessed portion, corresponding to the region of the magnetic disk surface which the actuator arm does not traverse, and the surface of the magnetic disk is made as narrow as possible. The air flow generated in that space by the rotation of the magnetic disk is thereby suppressed and as a result, magnetic disk resonance is suppressed. Also, the noise level is further suppressed by having two layers of damping plates attached to the outer surface of the cover.

摘要： A magnetic disk device comprises a magnetic disk in which a data zone is formed. An actuator has a voice coil and a head slider carrying a magnetic head, the actuator being swung to move the magnetic head over the disk between an innermost position of the data zone and an outermost position of the data zone. A magnet has a magnetization center and is opposed to the voice coil so that a voice coil motor which swings the actuator is formed, the magnet having a north pole and a south pole confronting each other via the magnetization center. The magnetic disk device is provided so that a deviation of a center of the voice coil from the magnetization center when the magnetic head is in the innermost position of the data zone is substantially equal to a deviation of the center of the voice coil from the magnetization center when the magnetic head is in the outermost position of the data zone.
