banda magnetica MB20 | AB20 con codifica incrementale o assoluta
layout banda magnetica
A il nastro di copertura viene utilizzato per la protezione meccanica della banda magnetica e viene incollato sulla banda magnetica dopo l'installazione
B la banda magnetica è in plastica
C protegge da danni meccanici e riflette le onde magnetiche per aumentare il campo magnetico della banda

Electrical DatA
| Pole length | see type designation |
| Number of tracks | see type designation |
| Influence of external magnets | external magnetic fields must not exceed 64 mT (640 Oe; 52kA/m) at the surface of the magnetic tape. Higher values will damage or destroy the magnetic tape code. Magnetic fields > 1 mT at the measuring system has negative influences on the accuracy of the system |
