Chamber, at least for the transport of workpieces, a chamber combination, a vacuum treatment facility as well as a transport method
First Claim
1. A method for treating a non-magnetic workpiece by a vacuum treatment, comprising the steps of:
- (a) providing a vacuum treatment chamber for said workpiece;
(b) providing a transport arrangement for said workpiece in vacuum and comprising a part of magnetic material;
(c) applying said workpiece adjacent to said part of magnetic material;
(d) clamping said workpiece towards said part of magnetic material by applying, opposite to said part of magnetic material and with respect to said workpiece, a member comprised of magnetic material onto said workpiece and adjacent to said part of magnetic material of the transport arrangement; and
(e) conveying said workpiece to or from said treatment chamber by said transport arrangement with said workpiece clamped thereon.

Abstract
At least one chamber is provided for transport of workpieces such as storage disks, at least at times, into the vacuum atmosphere, during their manufacturing and comprises at least two exterior openings for the guiding-through of a workpiece. A majority of workpiece-receiving devices can be rotated jointly about an axis. At least one transport element is provided and is aligned with an opening. The transport element is disposed in the chamber independently of the rotatable workpiece-receiving devices and can be moved out and back in a radially controlled manner in at least one component, and engages on a workpiece in the opening area. A transport method for workpieces in an evacuatable chamber provides that at least two workpieces are rotated about a center in a plane of rotation and are displaced individually in a radial manner with respect to the center of rotation at least in one movement component.
