Abstract:
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.
