This is a catalog for Sony's Betamax video decks. Models featured: Beta Plus SL-HFR60 Beta Plus SL-HFR30 Hi-Fi Processor HFP-100 Video cameras are also included. Seiko Matsuda is on the cover. The nickname "Beta Plus" is probably not well-known, but it refers to a video deck that, while not Hi-Fi on its own, becomes Hi-Fi compatible when used with the separately sold Hi-Fi processor. Hi-Fi decks were expensive at the time, so Sony's proposal was to first purchase an affordable non-Hi-Fi deck and then upgrade to Hi-Fi later. This could be a valuable resource for understanding the history of Sony's Betamax. A store stamp is present. Please examine the photos carefully and bid only if you are satisfied. #Halloween on Mercari
