Abstract
Official abstract text for this publication.
Provided is a method of manufacturing a magnetic recording mediums comprising employing a lifting and drying device for cleaning substrates by immersing one or more disk-like substrates with a central hole into a cleaning liquid disposed in a cleaning tank and lifting and drying the substrates, the lifting and drying device including: a hanger mechanism that is inserted through the central hole of the substrates and supports a plurality of the substrates while being hung thereon; an elevation mechanism that elevates the hanger mechanism between a position where the substrates are immersed into the cleaning liquid inside the cleaning tank and a position where the substrates are lifted from the cleaning tank; and an ejection mechanism that is disposed in the cleaning tank and ejects the cleaning liquid from the downside of the hanger mechanism toward the substrate.
First claim
Opening claim text (preview).
