Abstract

At the rate which areal density is advancing, the drive designer expects to encounter the superparamagnetic limit somewhere between 20 and 40 Gbpsi. In this paper, we review several new near-field magneto-optical recordings for high- capacity storage technology and their optical characteristics. We also will present novel head designs. The HGA (Head Gimbal Assembly) consists of a miniature slider body, objective, solid-immersion lens and a planar writing coil mounted underneath the slider in a flying height of few micro inches above the media. We will discuss aspects of the near field optical recording technology, along with some physics.
