The UD 35-90 is a sound recording tape for professional use on reel-to-reel tape recorders. It is a very reliable tape with high specifications for studio use. This tape is 35 microns in total thickness, consisting of a thick layer of ferromagnetic particles, which should reduce the chances of any dropouts occurring. It has a high output extended range, low noise formula, and a standard hub spool. The total length of 550 m lasts 96 minutes (both sides) at 19 cm/s speed.
Providing the tape has been stored in a cool dry place, and looked after, it will work well. Even the older tapes of the 1980s era tend to work well without any 'sticky' problems, or squeaking noises. This is the reason why this tape seems to be holding its price even in the second hand market such as eBay. Back in the 1980s, many prominent manufacturers of reel-to-reel decks designed their transport mechanism and electronics to work with the Maxell tape, and many people therefore still use Maxell as a result.
Sound Recording Tape
I recorded a digitally modified soundtrack of the “Gladiator” with boosted bass and tone and it sounds amazing with signal levels near saturation. I love the sound extra low bass and high tone that it is able to reproduce.
These tapes come in a clear plastic spool. It is a very tough acrylic plastic spool hub. They seem to last forever without any problems.
Maxell are always improving their tape product line with small enhancements and this series of tape came in slightly different specifications such as the early 35-90B, or newer tapes 35-90BN and 35-90N. The good thing is that they have the same high quality and reliability I have come to know of Maxell.

This is the iconic Maxell logo on the tape. I have never had any problems with their tapes and I usually stock the museums archive with these.
