Magnetic Microstructure and Media Noise of Thin Film Media Fabricated under Ultra Clean Sputtering Process

Dry and Wet Wear Characteristic of TiO2 Thin Film Prepared by Magnetic Sputtering in Ringer Solution

In this research, a thin film of TiO2 was applied on AZ91D using the method of magnetic sputtering. Microstructure investigations were done using field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). Wear resistance for the coating was investigated using the pin on the disk in the form of dry and in the Ringer's solution. After this test, the worn surface of the sampl...

HITPERM soft-magnetic underlayers for perpendicular thin film media

A class of nanocrystalline alloys, HITPERM ~Fe, Co!–M–B–Cu (M5Zr,Hf,Nb, etc.! found to exhibit excellent soft-magnetic properties is being studied for use as a soft-magnetic underlayer for perpendicular recording media. Previously, we reported that HITPERM films of ;100 nm thickness sputtered at room temperature ~RT! and at ;2.3 W/cm power density had exhibited an amorphous microstructure, whic...

Thin Film Media II M. Russak, Chairman FeAl underlayers for CoCrPt thin film longitudinal media

B2 ordered FeAl films with a small, uniform grain size have been produced by rf diode sputter deposition on glass substrates. CoCrPt films grown on FeAl underlayers were found to have the ~101̄0! lamellar texture. The in-plane coercivities (Hc) of the CoCrPt/FeAl films are comparable to those of the CoCrPt/Cr films and they can be further improved by inserting a thin Cr intermediate layer betwee...
