Visual Investigation on the Head-Tape Interface in a HDTV Digital Baseband VCR
The spacing between a multi-channel cluster head and the magnetic tape has been investigated by using transparent dummy heads and an original image processing method to develop a 1.2 Gbps HDTV digital baseband VCR. The influence of the head projection and tape tension on the head-tape spacing in a cluster head system, which was unknown before, has been made clear. The authors found the effective improvements to reduce the head-tape spacing of the individual heads of a cluster, and to realize a low tape tension VCR system.
