We studied the rate of degradation of the data storage capability of three commercial and two experimental metal particle (MP) tapes in an impinging jet geometry designed to eliminate irreproducibility in accelerated atmospheric testing. Both the bul

Different metal evaporated (ME) media were compared to investigate the cause of the temperature dependence of coercivity for ME media. It was found that exchange coupling and the temperature dependence of coercivity near room temperature are separate

The corrosion behavior of Metal Evaporated (ME) and Metal Particle (MP) media in a mixed corrosive gas environment was studied using microscopic techniques. Combined AFM and MFM studies showed severe corrosion of ME tape. Auger and EDAX spectroscopic

The dependence of the magnetic properties of reactively evaporated Co on film thickness and oxygen pressure have been studied. The coercivity was found to be very sensitive to oxygen pressure, but the coercive squareness and coercivity peak at differ

The effects of high temperature long-term aging on the erasability of various high coercivity tape media were investigated. The results showed that Co- gamma -Fe/sub 2/O/sub 3/ media, depending on how they were prepared, could become increasingly har

A series of barium ferrite disks with a variation in volumetric packing density from 1.5% to 35% were investigated to determine the effect of interparticle interactions on the switching field distribution (SFD) of the media. Kelly et al. (1989) intro

Ferromagnetic resonance (FMR) was used to characterize particles dispersed in a nonmagnetic matrix. A sequence of media was prepared in which high-aspect-ratio CrO/sub 2/ particles were dispersed in a binder matrix with volumetric packing fractions (
