These cassettes are exceptionally durable because a special high adhesion treatment locks its ultra-fine Super Finavinx high-performance metal alloy magnetic layer and backcoat to the base film. With these advanced technologies and the use of a high-precision, heat- and shock-proof mechanism, TDK MP Premium 8mm cassettes can stand up to the toughest use in any environment. Whether you own an analog or digital camcorder, TDK has the right tape for you. This is a two-pack of Hi-8 120-minute 8-mm video tapes.
