The Sony D1M-34A Digital D1 Video Cassette, Medium Shell is part of the D-1A series of video tapes. The D-1A series has improvements in the magnetic particles, binder system, and backcoating that add up to greater reliability. Hi-packing technology and powerful magnetic particles mean retentivity is now 25% higher, coercivity is 5.0% higher, and RF output is 2dB higher than the previous D-1 tape. Because of the magnetic layer's high output characteristics and optimized tape surface design, rubbing noise has been reduced.
