MDS-36 is the latest addition to the ATR Magnetics line of audio recording products. MDS-36 is the long-playing version of our ATR Master Tape that engineers and musicians have come to love. We named MDS-36 in commemoration of company founder and industry leader Michael D. Spitz. Coated on the highest quality 1.0 mil polyester film, MDS-36 provides excellent performance and reel-to-reel consistency. Our new formulation offers high output and low noise with improved recording economy, and is bias compatible with ATR Master Tape requiring minimal adjustment for optimal performance.
