Magnetic Tape MB20 | AB20 incremental or absolute coded
magnetic tape layout
A the cover tape is used for the mechanical protection of the magnetic tape and is glued onto the magnetic plastictape after installation
B magnetic tape band made of plastic
C magnetic conductable stainless steel tape protects from mechanical damages and is a magnetic short circuit
