## Description

desertcart.com: RTM C90 | Type One 90 Minute Blank Music Cassette | Ideal for Audio Recording | Studio Quality | Single Cassette : Electronics

Review: Very amazing tape, for a type 1, buy them! - These are great tapes! Very low noise, even without noise reduction Dolby B/C initiated. These are so much better than what I used decades ago. (like 4 decades ago) Is the price a little higher yes, is it worth it definitely! If it’s in your budget get these.
Review: High End Modern Tape! - RTM quality is unmatched in the reel to reel world. It's no wonder that these cassettes are so good. They are a shining star in the malaise of new cassettes...with Type II and IV tapes long gone, the best anyone can hope for is a manufacturer making a good tape. THIS IS THE TAPE. If you have a high end deck and insist on new tape, you won't be disappointed by these. Both this and the 60 minute version are solid. Calibration on a high end deck tells most of the story. It's not a superferric, but it does have a high MOL and a very consistent coating. Background hiss levels are acceptable, especially considering the MOL. HIGHLY RECOMMENDED

### ⭐⭐⭐⭐ Rtm 90 minute blank cassette tapes
*by L***E on February 3, 2026*

So I purchased the 3 pack of RTM c90 blank cassette tapes I heard a lot of good reviews about them so I ordered them so the first one I opened I put it in my cassette deck to get it ready for recording I always fast forward and rewind a tape so I know there's not any slack in the unit when it got to the end of the tape the tape got tangled inside and I carefully open it because there was five screws to access my wife helped me put it back together so I proceeded to record from a CD and at the end of the tape it did it again just recording so I threw it away was pretty disappointed in that one so I opened the second one fast forward it and then rewound it and then I recorded side a and side b and that one seems to be okay very good quality sound not sure what happened with the first one I guess just a defective unit.
