Now, however, a company whose name is synonymous with the very highest quality in cassette-playing equipment, Nakamichi, has gone into the cassette recording business and has just issued the first two dozen tapes in its new undertaking. Calling its new tapes the Reference Recording Series, Nakamichi has licensed recordings from some major audiophile disk manufacturers and duplicated them in real time on TDK metal tape, with each tape recorded while in its final shell, rather than recorded first and then wound into plastic shells.
Nakamichi says its tapes have a flat frequency response of 20 to 20,000 hertz and a dynamic range of over 90 db. Each cassette is available either with Dolby B noise reduction (which is standard on most cassette decks) or Dolby C, the newer and improved system. Further, and of special interest to those with automatic-reverse decks, the tapes are designed so that there is little or no blank space at the end of each side. The tapes will be sold through Nakamichi's aquipment retailers.
