Tapes affected by sticky-shed are those that were made by Ampex/Quantegy such as 406/407, 456/457, 499, and consumer/audiophile grade back coated tapes such as Grand Master and 20-20+, [citation needed] as well as those made by Scotch/3M including professional tapes such as 206/207, 226/227, 262 (though not all 262 is backcoated and therefore isn't affected), 808, and 986 as well as audiophile ...
The tape is then rewound. The average seek time is 2 seconds [3]: 11 and the storage space is 2560 kilobytes. [4] The control system is operated by transistors. Both the carousel and individual spools are replaceable. [1] The magnetic tape is a 5/8-inch (1.6 cm) wide and 0.05 mm thick Mylar 3M Co type 188.
A reel-to-reel tape recorder (Sony TC-630), typical of a 1970s audiophile device. Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the supply reel (or feed reel) containing the tape is placed on a spindle or hub.
In isolation, Kapton remains stable across a wide range of temperatures, from 4 to 673 K (−269 to +400 °C). [5] [6]The thermal conductivity of Kapton at temperatures from 0.5 to 5 Kelvin is rather high for such low temperatures, κ = 4.638×10 −3 T 0.5678 W·m −1 ·K −1.
The wire is glued to the mylar with 3M 77 spray adhesive, then sealed with 3M Fastbond 30NF (Magnepan used to use Milloxane to seal, but no more). Newer Magnepans use 30 μm (0.0012") thick 1/8" (3 mm) wide aluminum tape instead of wire. When the aluminum tape is used instead of wires, Magnepan calls the speakers "Quasi-Ribbons". [3]
[135] [136] The Knoxville plant is among 3M's largest and produces approximately 12,000 different products, including adhesives and tapes.
