TDK CD'ing II is a high-output, high-resolution Avilyn™ Type II (high bias) formulation specially engineered to ensure faithful CD reproduction. Because of its exceptionally wide dynamic range and low noise, CD'ing II is ideal for CD recording and sound reproduction, even in the limited environment of boomboxes, mini systems, dual-well cassette decks and portable personal stereos. The key to CD'ing II's superior recording characteristics rests in TDK's use of finer, more uniform Avilyn magnetic particles, an advanced binder system and TDK's HP-AR High Precision Anti-Resonance cassette mechanism. TDK CD'ing II cassettes are available in 60, 90 and 110 minute lengths.
