這篇 EQ 雜誌文章是關於Digital Format 的歷史演進，還有格式過多的問題，從早期SONY和Mitsubishi等公司開發數位多軌錄音到近年的 ADAT、DA88 和硬碟錄音等。有興趣的人可以一讀。 http://www.eqmag.com/1001/column_nichols_111.shtml <BLOCKQUOTE>quote:</font><HR> Continuing on with our format coverage, we'll start with Mitsubishi's foray into the future of digital audio. In 1983, I got to use the first Mitsubishi X-800 32-track, one-inch digital machine, and their X-80 reel-to-reel two-track digital recorder. The first project to be recorded on the X-800 was John Denver's One World [BMG/RCA, 1986] featuring Bob Marley's band The Wailers, recorded at Criteria Recording Studios in Miami. We mixed to the X-80 two-track and mastered with Bob Ludwig at Masterdisk in New York. The second-generation digital machines had ten times better error correction, and all of the tracks were on the same head to avoid the error-prone physical adjustments that needed to be done with the 3M machines. Mitsubishi later improved and shrunk the 32-track machine with the X-850 and, later, the X-880 32-track machines. Otari licensed the PD (ProDigi) format from Mitsubishi and produced the D-900 machine, which would record and play Mitsubishi 32-track tapes. <HR></BLOCKQUOTE>
