In the "olden days," radio stations played music from vinyl records on turn tables. These were alternatively called disks. So, the disk jockey was the one who "jockeyed" the disks onto the turntable and introduced the songs. The term remained as playing music shifted to tapes, CDs and, now, I suspect onto computers.
