Embodiment Construction

[0035] Referring to FIGS. 1 and 2 , a spin stand 1 includes a platform 2 . The platform 2 may be made of granite, and may be mounted on a vibration isolation stand (not shown) to isolate the spin stand 1 from external vibrations.

[0036] The spin stand 1 has a bridge 3 mounted on a platform 2 . The bridge part 3 supports the spindle assembly 4 to keep the disk 5 to be tested upside down, that is, the end of the spindle assembly 4 that fixes the disk 5 is located at the bottom. It can be clearly seen from FIG. 2 that the spin stand 1 also has a disk switch 6 . The spindle assembly 4 and disk changer 6 will be described further below.

[0037] Platform 2 also has a movable table for holding read / write heads 8 to be tested. The read / write head 8 is incorporated into a head gimbal assembly (HGA). In an embodiment as shown in the accompanying drawings, the movable worktable comprises a disk 7, or is a disk 7, and the disk 7 is used to hold a magnetic head 8 supported on the su...

Abstract

In one arrangement, apparatus for attaching a disk to a spindle of a spinstand has a spindle adapter. The spindle adapter has a drawbar movably disposed within. The drawbar has a connector end that is reversibly connectable to the cap and has a piston that is connectable to a source of fluid pressure. The drawbar is movable in response to fluid pressure so as to urge together the cap and the spindle adapter when connected. The cap and the spindle adapter are capable of holding a said disk therebetween. In another arrangement, a movable stage movable over a deck of a spinstand has a lift stagearranged to hold a cap with a disk positioned thereon. The lift stage has at least one actuator for raising the lift stage so that the cap can be connected with a spindle adapter of an inverted spindle of a spinstand.

Description

technical field [0001] The present invention relates to a device for attaching a magnetic disk to the spindle of a spinstand, a method for attaching or detaching a magnetic disk to or from the spindle of a spinstand, and a movable Workbench (movable stage). Background technique [0002] It is known to use a spin stand to test various components of a hard disk assembly, especially components such as read / write heads and disk media. Such testing can be done in a manufacturing production environment where typically each head and partial disk is tested before being assembled into a hard disk assembly to ensure that they perform to the required standard. Testing with a spin stand can also be done in an R&D setting. [0003] A spin stand typically includes a platform (eg, of granite) that is usually insulated in some way from external vibration sources so that these vibration sources do not affect the accuracy of the test results. A spindle is attached to the platform to hold a...
