摘要

Hybrid recording could become an option for continued areal density growth when conventional recording faces limitations due to the thermal stability of the medium. It can enhance the areal density achieved by conventional longitudinal and perpendicular recording, on continuous or on patterned media. In this paper we have discussed the desired medium properties and the desired properties of an integrated optical magnetic head. Their realization will be a big challenge. However, this may be worth the effort, because, as shown in section 2, under not too unrealistic conditions the areal density advantage can be a factor 5 or more. In combination with this advantage the saturation magnetization (and remanence) at the storage temperature can be much higher, leading to a higher readback signal. Key scientific questions are: (ⅰ) is the Arrhenius-Neel-Brown model applicable in the frequency range above 1 GHz? (ⅱ) is the model applicable to (layered) amorphous RE-TM type films for perpendicular recording, in which there are no separate crystal grains? (ⅲ) How does the attempt rate (in particular: the damping parameter a) vary with temperature? We have discussed our experimental results, and have indicated what experimental steps should be taken next. Finally, we remark that hybrid recording may also be extended to thermally assisted read-out [3,4]. This will give rise to new advantages, and will introduce new requirements, not discussed in this paper.
