Title:
RECORDING DEVICE, READING DEVICE, RECORDING METHOD, RECORDING PROGRAM, READING METHOD, READING PROGRAM, AND MAGNETIC TAPE
Document Type and Number:
WIPO Patent Application WO/2020/183898
Kind Code:
A1
Abstract:
This information processing device comprises: a generation unit generating, from information regarding each of a plurality of pieces of data designated for recording, a ranking of groups for classifying each piece of data; and a control unit performing control for recording on a magnetic recording medium, for each topmost rank group, the plurality of pieces of data contained in the topmost rank group, in a recording order which follows the ranking from the top to the bottom. The magnetic recording medium has a magnetic layer including a ferromagnetic powder and a binder on a nonmagnetic support and, as measured by optical interferometry on the magnetic layer surface after washing with n-hexane and under pressure forces of 0.5 atm and 13.5 atm, the difference between the spacings S0.5 and S13.5 is 3.0 nm or less.
