Document Type and Number:
WIPO Patent Application WO/2023/100879
Kind Code:
A1
Abstract:
Provided is a magnetic tape having a non-magnetic support and a magnetic layer containing a ferromagnetic powder. The non-magnetic support is a polyethylene naphthalate support that has a Young's modulus of at least 10,000 MPa in the width direction. The ratio (AlFeSil wear value 2 / AlFeSil wear value 1) of the change in the AlFeSil wear value before and after storing of the tape, as measured for the surface of the magnetic layer in an environment having a temperature of 23°C and a relative humidity of 50%, is at least 0.7. Also provided are a magnetic tape cartridge and a magnetic tape device that include the magnetic tape.
