Mitsubishi / MGA Blank Cassette Tapes

Mitsubishi Electric Corporation entered the consumer audio market under the MGA brand name - MGA standing for Mitsubishi's consumer audio division - producing cassette tapes, cassette decks, and audio components primarily for the Japanese domestic and US export markets. The MGA brand was used for North American distribution of Mitsubishi audio products through the 1970s and 1980s.

Mitsubishi's relationship with blank cassette tape spans several product lines. The MGA �2 series (the name referencing the two-sided nature of the cassette format) offered a range of Type I normal bias cassettes with polyester-type base film and magnetic coating suited for general recording use. The Mitsubishi Black Diamond cassette was the brand's premium offering, available in C60, C90, and C120 formats. Mitsubishi also produced blank cassettes under the Verbatim brand - the Verbatim name being a Mitsubishi subsidiary focused on data storage media, well-known among collectors for its CD-R and DVD-R disc quality.

Mitsubishi cassette decks, sold under the MGA and Diatone brands, included several technically ambitious three-head designs. Notable models include the DT-30 and DT-40, both three-head, closed-loop dual-capstan decks with internal frequency generators for calibration - among the more sophisticated Japanese cassette transports of their era.
