Later I recall Sharp had some sort of specially treated diamond-hardened surface or somesuch of the upper drum they touted. Those old ones were solid brass I was talking about. The mass served as a flywheel too. Take one off and it's heavy unlike the usual aluminum alloy. And that belt drive arrangement. Oddly the "Inventor" of VHS, JVC, used a belt drive head drum on their first home VCR, the HR-3300, but that belt was on the bottom of the deck. One thing about Matsushita (parent company of JVC) they always used a DD cylinder from their first PV-1000.
