MAGNETIC RECORDING MEDIUM AND CARTRIDGE

Abstract:

[Object] To provide a technology capable of further improving the recording density of data. [Solving Means] A magnetic recording medium according to the present technology is a tape-shaped magnetic recording medium including: a base material; and a magnetic layer, the tape-shaped magnetic recording medium being long in a longitudinal direction and short in a width direction, in which the magnetic layer includes a data band long in the longitudinal direction and a servo band long in the longitudinal direction, a data signal being written to the data band, a servo signal being written to the servo band, the degree of perpendicular orientation of the magnetic layer being 65% or more, a full width at half maximum of an isolated waveform in a reproduced waveform of the data signal is 185 nm or less, a thickness of the magnetic layer is 90 nm or less, and a thickness of the base material is 4.2 .mu.m or less.
