摘要：

A new type of glass-ceramic disk substrate material: lithium disilicate glass:TS-10 with a built-in auto-texture induced by its intrinsic crystalline phase nature has been investigated. Sub 1-microinch glide height performance was evaluated by the glide avalanche method showed that the TS-10 thin-film disks are free of hits down to 0.7 microinch. In contact-start-stop(CSS) tests, the stiction forces did not show increase during 20K CSS cycles and produced good CSS performance at 3 lube thicknesses. Corrosion testing of TS-10:CoNiCr disks was conducted under stressed environmental conditions. Missing-pulse errors measured before and after corrosion testing did not show significant increase and the optical microscopic inspection did not show corrosion spots. Also, the shock-resistance testing results demonstrated that the TS-10 thin-film disks can withstand high shock-loads upto 1000 g-level suitable for mobile drives without showing cracking or head-slap.
