“…This tremendous potential in perpendicular magnetic recording should be extensible to a track density, because the magnetization transition on a recording track edge should be very sharp as same as that in the head moving direction [15]. Since the diameter of a Co-Cr crystalline-particle is about one tenth of the film thickness [16], an areal density close to or over 0.5 Gbits/mm 2 will be achievable on a Co-Cr recording layer of around 0.1 microns in thickness. This areal density corresponds to a recorded area which is less than the square of about 50 nm x 50 nm per onc bit as shown in Fig.…”

--In magnetic recording, information data is written by the perpendicular magnetization component even in a longitudinally oriented recording medium, especially when it consists of non-interacting fine magnetic particles. The future prospect of magnetic recording has been theoretically investigated using a computer simulation from the viewpoint of media having both higher recording resolution and higher output. Recording bit density over 500 kFCI accompanied with higher surface flux density has been confirmed in perpendicular magnetic recording not only by experiments but also by computer simulations. Novel techniques on head-to-medium interfaces and very narrow track single-pole heads for a hard disk magnetic recording system have been also discussed to materialize ultra-high density perpendicular magnetic recording.
