What This Cassette Is

The RTM Type One is a 90-minute blank music cassette built on the BASF Studio Master 900 formula. It is made for musicians, podcasters and home recordists who want professional analog sound on tape. Each unit is manufactured in Normandy with a reinforced screwed shell and UV-printed labels.

Installation and Common Issues

Using the cassette is straightforward: load it into any standard deck, set bias for Type I tape and press record. The thicker substrate keeps linear speed stable and reduces print-through during long storage. The only common problem is accidental erasure if the write-protect tabs are left intact after recording.

Who Should Buy and Who Should Not

This suits anyone recording music, voice memos or mixtapes who values durability and consistent studio-grade performance. Buyers needing longer continuous runtime than 90 minutes or a different tape formulation should look at other options.
