==16 and 24-track recorders==
In 1966, Ampex built their first 16-track recorder, the model AG-1000, at the request of Mirasound Studios in New York City. In 1967, Ampex introduced a 16-track version of the MM 1000 which was the world's first 16-track professional tape recorder put into mass-production. Both used a {{convert|2|in||adj=on}} tape transport design adapted from the video recording division. The 16-track MM-1000 quickly became legendary for its tremendous flexibility, reliability and outstanding sound quality. This brought about the "golden age" of large format analog multitrack recorders which would last into the mid-1990s. [[Music Center Incorporated|MCI]] built the first 24-track recorder (using 2-inch tape) in 1968 which was installed at [[TTG Studios]] in Los Angeles. Later machines built by Ampex starting in 1969 would have as many as 24 tracks on 2 inch tape. In addition to this, the introduction of [[SMPTE time code]] allowed studios to run multiple machines in perfect synchronization, making the number of available tracks virtually unlimited.

By the 1970s, Ampex faced tough competition from the Swiss company [[Studer]] and Japanese manufacturers such as Otari and Sony (who also purchased the MCI brand in 1982). In 1979, Ampex introduced their most advanced 24-track recorder, the model ATR-124. The ATR-124 was ruggedly constructed and had audio specifications that nearly rivaled the first [[digital recording]] machines. However, sales of the ATR-124 were slow due to the machine's high price tag. Ampex sold only about 50 or 60 ATR-124 machines and withdrew from the professional audio tape recorder market entirely in 1983.
