Approaches to tilted hard disk magnetic recording for extremely high areal density

摘要

Longitudinal magnetic recording may meet its limits including the wide writing track and thermal instability, etc, around 300 Gbit/in{sup}2. A tilted magnetic recording based on micromagnetic simulation was proposed to extend the longitudinal magnetic recording. Perpendicular recording was proposed about 20 years ago. It is always considered as a promising candidate for ultrahigh density magnetic recording.
