Abstract: PROBLEM TO BE SOLVED: To directly deal with a robot for assembly of horizontally moving type having access from the upper side toward the lower side. SOLUTION: A plurality of supporting seats 20 are formed on a tray 10, and a hard disk 60 is mounted thereon by the supporting seats 20, and a central section of the hard disk 60 is pressed elastically by a press member 42 attached to the lower face of the upper tray 10, and such trays 10 are stacked in a plurality of stages, and a bottom plate 11 is combined with the lower side of a lowermost tray 10, while a cover plate 12 is combined with the upper side of an uppermost tray 10, and the whole assembly is clamped by engaging members formed of leaf springs from both sides.

Abstract: PROBLEM TO BE SOLVED: To eliminate generation of thermal asperity and to avoid generation of error by making head vibration have a directional component approaching the disk surface. SOLUTION: When an error is generated, a vibration signal from a means 52 is superposed on a signal from a controller 43 by a direction of HDC and supplied to a VCM driving means 45. And a head 20 is positioned at a desired position according to thermal asperity position. By providing the VCM 46 with a vibration signal, a head assembly starts rolling movement centering the joint point with a dimple. And the head assembly generates vertical vibration with a frequency equivalent to the given vibration signal frequency, and eliminate the thermal asperity on the disk.
