Abstract
A disk carrier is comprised of a carrier plate having one or more throughholes at which disks are carried with both surfaces exposed to be processed. Abutting and partially around each of these throughholes is a recess such that not only can a disk be easily positioned at the throughhole without having its surface scratched but also a corner is formed in this recessed region which can serve as an indexing depression. For this purpose, the recess may be fomed with a bottom surface parallel to the surface of the carrier plate and boundary wall in the form of a part of a polygon such that two mutually adjacent straight parts thereof, together with the bottom surface, form a corner which can serve as a reference position easily accessible by a touch sensor.
