Title:
磁気テープ、磁気テープカートリッジおよび磁気テープ装置
Document Type and Number:
Japanese Patent JP7091264
Kind Code:
B2
Abstract:
The magnetic tape in which the followings are satisfied, after the magnetic layer is pressed at a pressure of 70 atm. A full width at half maximum of a spacing distribution measured by optical interferometry regarding a surface of the magnetic layer before performing a vacuum heating with respect to the magnetic tape is greater than 0 nm and equal to or smaller than 15.0 nm; a full width at half maximum of a spacing distribution measured after performing the vacuum heating is greater than 0 nm and equal to or smaller than 15.0 nm; and a difference (Safter−Sbefore) between a spacing Safter measured by optical interferometry regarding the surface of the magnetic layer after performing the vacuum heating with respect to the magnetic tape and a spacing Sbefore measured before performing the vacuum heating is greater than 0 nm and equal to or smaller than 12.0 nm.
