Abstract :
The possibility of realizing linear magnetic recording systems over 15 Gb/in2 recording density has been shown in our test with newly developed metal particulate (MP) tape using 35-nm-size fine metal particles and a GMR head designed for hard disk drive (HDD). It was done under a read-track-base calculation with the following media: magnetic layer thickness =60 nm, surface roughness Ra=2.0 nm.
