ABSTRACT

To attract a workpiece with a limited contact region, e.g., a doughnut-shaped
compact disc having a central circular hole, a skirt of a substantially
arcuate attractor is held against an annular land extending around the central
circular hole. Suction forces are applied through a plurality of suction holes
surrounded by the skirt to attract the annular land for attracting and
carrying the compact disc. A mini disc having an annular step along a
peripheral region around a central hole thereof may stably be attracted and
carried by an attractor having inner and outer annular contact members which
axially project different distances to contact the peripheral region and an
area, respectively, that is radially spaced from the peripheral region by the
annular step.
