Toto IV is the fourth studio album by American rock band Toto, released on April 1, 1982, by Columbia Records. The album's lead single, "Rosanna", peaked at number 2 for five weeks on the Billboard Hot 100 charts, while the album's third single, "Africa", topping the Hot 100 chart, became the group's first and only number 1 hit. Both songs were hits in the UK as well, reaching number 12 and 3, respectively. The fourth single, "I Won't Hold You Back", also peaked within the top ten on the Hot 100, at number 10 and atop the Billboard Adult Contemporary charts for three weeks.
The multiple 24-track recorders were linked via a computerized SMPTE timecode system. One track of each machine contained the timecode synchronization signal, while 22 of the remaining 23 tracks of each reel were available for audio track recordings. (Typically, on analog 24-track recorders SMPTE was recorded on track 24, and the track next to it left blank to avoid any cross-talk or bleed over from the time code.) A significant number of tracks were copied and mixed down from those already recorded on another synchronized tape reel. This process lowered the amount of wear on the first generation tapes and helped maintain high quality sound during the extensive overdubbing and mixing process.
