SYSTEM FOR FABRICATING A PATTERN ON MAGNETIC RECORDING MEDIA
An inline processing system for patterning magnetic recording layers on hard discs for use in a hard disc drive. Discs are processed on both sides simultaneously in a vertical orientation, in round plate-like holders called MDCs. A plurality (as many as 10) discs are held in a dial carrier of the MD...

Abstract | An inline processing system for patterning magnetic recording layers on hard discs for use in a hard disc drive. Discs are processed on both sides simultaneously in a vertical orientation, in round plate-like holders called MDCs. A plurality (as many as 10) discs are held in a dial carrier of the MDC, and transferred from one process station to another. The dial carrier of the MDC may be rotated and/or angled at up to 70° from normal in each process station, so that one or a plurality of process sources may treat the discs simultaneously. This configuration provides time savings and a reduction in the number and size of process sources needed. A mask enhancement process for patterning of magnetic media, and a filling and planarizing process used therewith, are also disclosed. |
