Abstract
The physics of the playback process in perpendicular magnetic recording was discussed. Three recording modes, longitudinal recording and perpendicular recording without and with a soft underlayer (SUL) were compared with a 10 nm thick recording layer at a bit aspect ratio of 1:1. It was found that the signal does not depend on the use of SUL at high densities.
