Document Type and Number:
WIPO Patent Application WO/2023/100876
Kind Code:
A1
Abstract:
Provided are a magnetic tape cartridge in which a magnetic tape is accommodated, and a magnetic recording playback device including the magnetic tape cartridge. For the magnetic tape, the maximum value of magnetic tape deformation amount after storage for one year in each of five environments is 0.50 μm or less, the rate of change in the magnetic tape deformation amount relative to a change in relative humidity derived from the five magnetic tape deformation amounts is 0.0001-0.0500 μm/% inclusive, and the rate of change in magnetic tape deformation amount relative to a change in temperature derived from the five magnetic tape deformation amounts is 0.0010-0.1000 μm/°C inclusive.
