AI Technical Summary

⚠Technical Problem

Magnetic tapes experience deformation during long-term storage, leading to off-track issues that reduce the operational stability of magnetic tape drives, particularly with increased track density.

⚗Method used

A magnetic tape with a non-magnetic support and a magnetic layer containing ferromagnetic powder, designed to minimize nonlinear tape width deformation to 100 nm or less after 10 days of storage, and a magnetic tape device with adjustable head tilt angles to compensate for dimensional changes.

🎯Benefits of technology

Improves the operational stability of magnetic tape drives during recording and playback after long-term storage by reducing off-track events and maintaining accurate data tracking.
