METHOD AND DEVICE FOR STABILIZING MAGNETIC TAPE CONVEYING AND MAGNETIC TAPE PROCESSING DEVICE

WIPO Patent Application WO/2001/020606

A1

A magnetic-tape-conveying stabilizing method and device, for stabilizing magnetic tape conveying by vacuumizing portions in front of and at the back of a magnetic tape support, by bringing the magnetic tape to the support by a magnetic force, and by providing an escaping groove for a tape-carried air layer in a support surface or by removing the carried air layer by a support edge. The method and the device for stabilizing width-direction conveying by urging a curved magnetic tape in its width direction or by using a collared roller, crown roller or concave roller. The method and the device for stabilizing vertical-direction conveying by detecting and correcting the vertical position of the magnetic tape, and by using a roller having a specified rotation accuracy or urging a magnetic-tape-conveying guiding portion to a reference position. Whereby, a magnetic tape processing device can process magnetic tape with a high accuracy by stabilizing magnetic conveying.
