TEAC O'Casse OC-2NA Extreme rare item and a real collectors item. Back in the 80s when the The Compact Cassette or Music cassette (MC) was the number one music format, several companies creates beautiful Cassettes copying the look of the reel to reel tapes! Then somewhere in the middle 80s the TEAC corporation creates the 'Open system cassette' (O'Casse) getting closer not only in appearance but also in the philosophy of reel to reel tapes! The result was an unusual cross between an open reel tape and the compact cassette. ​ Due to the small size needed extremely delicate handling to preparing it for use , and we think this was the reason that many people call it a very bad and worthless idea, but if we exclude the difficulties in use is a very beautiful reel tape miniature and most important... it plays!!! As far as we know the 'O'Casse' was only available in Japan.
