Sales were very low and specialized during the 1980s. Audiophile reel tapes were made under license by Barclay-Crocker between 1977 and 1986. Licensors included Philips, Deutsche Grammophon, Argo, Vanguard, Musical Heritage Society and L'Oiseau Lyre. Barclay-Crocker tapes were all Dolby encoded and some titles were also available in the dbx format. The majority of the catalog contained classical recordings, with a few jazz and movie soundtrack albums. Barclay-Crocker tapes were duplicated on modified Ampex 440 machines at four times the playing speed, unlike popular reel tapes which were duplicated at 16 times the playback speed. All of the known pre-recorded reel-to-reels on the market are all documented at the Reel To Reel Index website which focuses on the last reels made during the 1980s and includes photographs of all of them. David Winter also released the complete list of 1950s EMI and Barclay-Crocker tapes.
