## Long description

Recording The Masters RTM C90 is a 90-minute Type I (ferric) audio cassette designed for recording, playback and archiving on standard analog tape players.

It is intended for everyday music recording, mixtapes, transfer of digital files to analog tape and preservation of cassette collections.
Advantages
The RTM C90 offers a reliable ferric oxide formulation that provides stable biasing and predictable frequency response on Type I decks. Its 90-minute length allows longer continuous recordings without changing tapes.

Key specifications

 Tape type: Type I (ferric oxide)
 Recording time: 90 minutes (45 min per side)
 Intended use: Music recording, playback, archiving
 Compatibility: Standard cassette players and recorders supporting Type I tapes
How to use
Insert the cassette into a compatible Type I tape deck with the tape window facing the correct direction for playback or recording. For best results, set the recorder to the Type I or Normal bias setting. Use a moderate recording level to avoid tape saturation; consult your recorder's level meters and adjust input gain accordingly. Rewind and fast-forward as needed using the deck controls. Store recorded cassettes in a cool, dry place away from strong magnetic fields to preserve audio quality.
Usage recommendations
For consistent recording quality, allow new cassettes to run briefly at recording level before making important recordings to stabilize the tape transport and erase any manufacturing residuals. When archiving digital sources, monitor levels to avoid clipping and consider creating a reference digital backup of important recordings.
