Experimental Study of Structural Zone Model for Composite Thin Films in Magnetic Recording Media Application
Composite thin films are a new area of study with many applications, e.g. metal + oxide thin films in high density magnetic recording media. Engineering the processing, microstructure and properties of these thin films is of great importance. It has been found that microstructures of the thin films depend strongly on the oxide volume fraction and pressure during sputtering. Surface diffusion an...
متن کاملExperimental Tetrahedral Recording: Part Two
Reproduced from Studio Sound, Vol. 13, pp 472, 473 and 475 (September 1971), by permission of IPC Media Ltd, publishers of Hi-Fi News (www.hifinews.co.uk 1 By Michael Gerzon LAST month we described the actual set-up for a recent experimental tetrahedral recording and noted initial listener reactions. Perhaps more important than describing any one particular experiment is to indicate the problem...
متن کاملNoise in Disk Data-Recording Media
Measurements were made of recording medium noise in erased disks using an in-contact magnetoresistive element and an inductive head supported on an air bearing slider. Four types of coatings on aluminum disks were examined: thin, transition-metal alloy film, CrO,, FeCo particle, a n d y-Fe,O:,. Results obtained by means of three measurement techniques are in qualitative agreement and indicate t...
متن کاملHigh Anisotropy CoPtCrB Magnetic Recording Media
We describe the synthesis, magnetism and structure of CoPtCrB alloys with Pt concentrations from 10 43 %. The Cr concentration in the alloys was 15-17 % and the B concentration was 9-11 %. The magnetic anisotropy and coercivity increase with increasing Pt up to M 30%, plateau at M 35,000 Oe and w 6000 Oe, respectively, and then decrease. Transmission electron microscopy results show the media f...
متن کاملRecording performances in perpendicular magnetic patterned media
We report on the recording performances and signal-to-noise ratio analyses of perpendicular magnetic bit-patterned media. Two different types of magnetic samples are investigated. They differ by the way that they were patterned (nano-imprint versus e-beam lithography) as well as their magnetic properties (Co/Pt multilayers and CoCrPt alloy are the recording layers). By using a contact read/writ...
