摘要： To provide a magnetic recording tape that exhibits excellent tape dimension stability even if there are changes in temperature or humidity or even if tension is applied to the magnetic recording tape during tape travelling.
The present technology provides a magnetic recording tape, the tape (T1 or T2) having a total thickness of 5.6 µm or less and including a magnetic layer 1, a non-magnetic layer 2, a base layer 3, and a back layer 4 in the stated order. In one embodiment, a deposition film layer A formed of a metal or an oxide thereof is provided on a lower-layer side of the non-magnetic layer 2. The deposition film layer A may be provided on the back layer 4 and an insulation layer B may also be provided between the deposition film layer A the non-magnetic layer 2.
