Early records were the "standard" three-minute version until Tom Moulton came up with a way to make songs longer so that he could take a crowd of dancers at a club to another level and keep them dancing longer. He found that it was impossible to make the 45-RPM vinyl singles of the time longer, as they could usually hold no more than five minutes of good-quality music. With the help of José Rodriguez, his remaster/mastering engineer, he pressed a single on a 10" disc instead of 7". They cut the next single on a 12" disc, the same format as a standard album. Moulton and Rodriguez discovered that these larger records could have much longer songs and remixes. 12" single records, also known as "Maxi singles", quickly became the standard format for all DJs of the disco genre.
