ATR Magnetics

P.O.A.

Quarter inch, two tracks ATR Master Tape running at 15 inches
per second (ips) involves approximately 80,000,000 oriented
and randomly stacked particles per track second. It’s not just
the particle count but the random stacking that turns this super
binary resolution into pure analog playback. This is why even
a narrow track width recording still sounds so detailed despite
the lower surface area.
