I can't seem to find this information with my google-fu, but does anyone know if magnetic tapes such as in vhs and cassette tapes have perpendicular magnetic anisotropy?
- reaperducer 8y agoI’m not entirely sure what it is that you’re asking. But if you’re asking if the heads for an audio cassette are angled, the answer is no. They’re perfectly perpendicular. For VHS, yes, they are angled. 30 degrees, IIRC. If that’s, indeed, what you’re asking.
- raziel2701 8y agoI was referring to whether the magnetization lies along the normal of the film/tape or if it's in plane. HDDs were able to increase density by moving to materials that had a magnetization with perpendicular anisotropy but I can't seem to find confirmation if cassette tapes and vhs had in plane anisotropy back then. More so I can't seem to find if today's magnetic tape storage has moved to perpendicular magnetic anisotropy. It seems
