In the late 1960s, magnetic recording began to be common in Czechoslovakia, yet the gramophone record as a storage medium continued to be concurrently improved too. During the course of the decade, magnetic recordings began to be released on tapes and audio cassettes. In Czechoslovakia, a number of titles were also produced on reel-to-reel tapes. The first tapes contained monophonic half- and four-track recordings, run at 9.5 cm/s. BASF, AGFA and Scotch tapes were used. Later on, in the 1980s, several dance music compilations were released on EMI tapes.
