19918 📃
A DENON Audio Tape gatefold leaflet, international release with no exact print date, 1991 is inferred from the lineup. Inside is the full range of the year: Metal HD-MS, High-bias HD8S/HD7S/HD6S on EX II purified black crystal and “XII-Maximized Metal” formulations, ferric DX4/DX3/DX1/DX and the DAT R-120DT with a new binder system at B.E.T. 55 m²/g. The middle panel shows the new shell with oblique dual windows and a length table covering everything from 46 to 120 minutes; the back carries full specs measured against a DENON tape tester deck.
- XII-Maximized Metal - XII-Maximized Metal - formulation used in DENON HD-MS, ultra-fine metal particles with high coercivity and uniform orientation
- EX II purified black crystal - EX II purified black crystal - fourth-generation evolution of the 1983 DENON process, metal particles at the core of the High-bias HD7S and HD8S
- B.E.T. 55 m²/g binder system - New binder system for the DAT R-120DT with dense packing of ultra-fine particles, B.E.T. specific surface area 55 m²/g
- Newly designed cassette shell - Shell with oblique dual windows and asymmetrically arranged centre bars to disperse resonances and minimize modulation noise
