-6
1/K
Bending Radius
min. 150 mm
Available lengths
32m (up to 70m on request)
Weight of the magnetic tape
ca. 62 g/m (inclusive adhesive tape + protective sheet)
Weight of the cover tape
ca. 19 g/m (inclusive adhesive tape + protective sheet)
Influence of external magnetic
fields
External magnetic fields are not allowed to exceed 64 mT (640 Oe; 52
kA/m) at the magnetic tape surface, because it can destroy and damage
the magnetic tape code.
Protection class
