Design of Metal Evaporated Tape for consumer digital VCR system.

Abstract

To determine the optimum electromagnetic characteristics of metal-evaporated tape for consumer digital VCR system, we tested the magnetic tapes with different spacing factors. It was found that higher retentivity (Br), corecivity (Hc) and a constant magnetic layer thickness are essential for low error rates. An advanced metal evaporated tape for a consumer digital VCR system was developed based on these findings.
