From the Manufacturer
These tapes use an ultrafine, Super Avilyn Type II, high-bias cobalt formulation with high-density packing and uniform orientation. They offer exceptionally high resolution, superior dynamic range, and very low noise, which makes them ideal for taping from a wide variety of music sources, including CDs. TDK SA tape employs the advanced AR-RC III mechanism for superior rigidity and reduced modulation noise, and is especially recommended for use in home component systems, high-performance portables, and car stereos. This is a five-pack of SA90 high bias cassettes.
