  recording density
In order to achieve a magnetic recording density of more than 1 Tb/in2, it is necessary to create an ultralow head-disk interface (HDI) spacing, i.e., less than 2-3 nm.
      
Due to increased recording density and lower flying heights, the stress placed on the HDI will require improved lubricant/carbon interaction for X-1P.
      
Even though the flying height is approaching molecular dimensions, it is expected to decrease as the areal recording density is increased.
      
A wide range of techniques for increasing the recording density and obtaining higher transfer rates are discussed.

A comparison between the polishing and calendering technologies is given, with the emphasis on the advantages of the calendering over the polishing. Significant improvements in the signal amplititude,the strength of medium layers and the wearability of the disks can be abtained with the calendering technology, resulting in thinner magnetic layer, higher recording density, higher signal to noise ratio and orientation degree. It is clear that the calendering technology is an important process to the fabrication...

Dispersion of γ-Fe_2O_3 powder in polymer solution plays an important role in gover-ning the recording density of magnetic recording materials. The wetting of the powders,disintegration of agglomerates and agglutination of particles are closely related to the surfacecharacteristics of γ-Fe_2O_3 powder. In this paper, the wetting characteristics and the appa-rent contact angles of γ-Fe_2O_3 powder in polar and non-polar liquids were estimated bydetermining the penetration rates of these liquids through powders, as well as the sedimen-tative volume of powders in liquids. Based on Fowkes' theoretical assumption,the valuesof the surface tension of γ-Fe_2O_3 powder were calculated: γ_s~d= 24 dyn/cm,γ_s~p=17dyn/cmand γ_s=41dyn/cm.

要提高磁带、磁盘等磁记录材料的记录密度,“分散”问题是关键之一,而分散过程中的润湿、磁粉团的解体和粒子的凝聚都直接与磁粉的表面特性有关。本文通过各种极性或非极性液体对密堆积磁粉的渗透速度以及磁粉在这些液体中沉降体积测定,研究了液体对磁粉的润湿特性,估测了它们的接触角;文内还尝试按Fowkes理论假定进行了计算,求得γ-Fe_2O_3磁粉表面张力为:γ_s~d=24dyn/cm,γ_s~p=17dyn/cm,γ_s=γ_s~d+γ_s~p=41dyn/cm。
