Ballen Record Company, Philadelphia, PA was founded by Ivin Ballen in 1946. Ivin built his own factory and studio from scratch. To keep his operation humming when his label’s acts were "cold", Ivin began to take in work from other established labels, and within a few years the business had become a full-time pressing plant for third party labels. Ivin Ballen passed away in 1978. Through the next two decades, the company (now called Disc Makers) progressed through various formats such as 45 rpm vinyl singles, 33 1/3 rpm vinyl LPs, 8-tracks, and audio cassettes. Today, Disc Makers stands alone as the undisputed leader in optical disc manufacturing for independent artists, filmmakers, and businesses.
