All tapes (except the T10) are recorded on the specially modified Revox B215 tape transport in a full-track configuration, using quality blank cassettes and the special Full-Track amorphous recording head from JRF Magnetics. Alignment tapes from BASF, STL, Teac, ABEX and Sony are used as primary references.

Each tape has a unique serial number and fully checked in both directions on two reference playback decks. Playback results are recorded on a computer for a full analysis and verification.
