    摘要: A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate having at least one surface; forming a layer of a sol-gel on the surface, partially drying the sol-gel layer at room temperature to remove a portion of the solvent therein to form a partially dried sol-gel layer of hardness less than that of the substrate; mechanically texturing the surface of the partially dried sol-gel layer; and depositing a layer stack including at least one magnetic layer thereover. Embodiments of the invention include embossing a servo pattern in the as-deposited sol-gel layer prior to partial drying and mechanically texturing, followed by sintering at an elevated temperature to form a substantially fully dried layer having a density and hardness similar to that of glass, and formation of a thin film magnetic media layer stack thereon.

    摘要: In a disk replicating assembly, a blank disk is attached to one platen and a stamper is attached to the other platen. Pressure is applied so that the two platens are forced together, thereby transferring features from the stamper to the disk. A ball joint is located between a platen and the pressure train of the replicating assembly. Due to the ball joint at this location, the resulting pressure gradient when the stamper and disk are pressed together causes the one platen to swivel such that it orients itself substantially parallel to the other platen. Because the resistance of the ball joint is selected so that the one platen is able to pivot before the stamper significantly affects the disk, the fine features of the stamper are not transferred to the disk until the platens are in parallel alignment.

    摘要翻译: 在磁盘复制组件中,空白盘连接到一个压板,并且压模附接到另一个压板。 施加压力使得两个压板被强制在一起,从而将特征从压模传送到盘。 球形接头位于压板和复制组件的压力列之间。 由于在该位置处的球接头,当压模和盘被压在一起时,产生的压力梯度使得一个压板旋转,使得其本身基本平行于另一个压板。 由于选择球窝接头的阻力,使得一个压板在压模显着影响盘之前能够枢转,所以压模的精细特征不会转移到盘上,直到压板平行排列。
