US 10,049,696 B2 · Optical recording medium production device and production method

Abstract

A recording medium production device includes a substrate positioning pin vertically movable that performs positioning to a center-hole of a substrate; a substrate holding portion that performs positioning of substrate using the substrate positioning pin to hold the substrate; a cleaner having a gas ejection portion that ejects gas toward the surface of the substrate held by the substrate holding portion, and a gas suction portion that suctions gas; and a substrate positioning pin fixing portion that can press the substrate positioning pin downward. The fixing portion is configured so as not to contact an inner circumferential side surface of the center-hole of substrate. The substrate positioning pin fixing portion descends inside the center-hole of substrate held by the substrate, and presses and fixes the substrate positioning pin. Then the cleaner performs ejection and suction of gas.

Claims6

Dependent claims

An optical recording medium production method comprising the steps of:

holding a substrate positioned by a substrate positioning pin vertically movable to a center hole of the substrate;
pressing the substrate positioning pin downward and fixing the same so as to expose an inner circumferential side surface of the center hole of the substrate;
and
removing a foreign material by a cleaner that ejects gas toward a surface of the held substrate and simultaneously suctions the gas.
