摘要： Disk substrates are polished in a process which uses a single load of the disks to a polishing apparatus and a single polishing slurry. Preferably, the process varies at least one polishing parameter at multiple stages to achieve both a reasonable rate of removal during one stage and a smooth finished surface during another stage. Preferably, a fine grit cerium oxide slurry is used, along with a polishing pad having surface characteristics intermediate those of relatively hard pads typically used for material removal, and of relatively soft pads typically used for fine finishing. The polisher operates at high pressure and speed during a material removal stage, and then reduces speed and pressure during a finishing stage to achieve a suitable surface finish, without removing and cleaning disks between the two stages.

摘要： A method of preparing for a disk polishing operation includes providing a polishing machine having a first and a second superposed platen. A first polishing pad is on the first platen and a second polishing pad is on the second platen. A plurality of carriers are disposed between the first and second polishing pads. Each carrier is adapted to rotate relative to the polishing pads and is adapted to carry at least one glass disk. A pressure, temperature and rotational speed of the polishing machine used during a disk polishing operation are determined. A number of diamond disks are provided. A diamond disk is placed in respective ones of the carriers. The polishing machine is operated at or near the determined pressure, temperature and rotational speed while simultaneously dressing the respective surfaces of the polishing pads using the diamond disks.

摘要： A polished glass disk is prepared for a magnetically recordable coating by texturing the surfaces with a highly abrasive material being abrasively engaged with the surfaces as the disk is rotated, thereby creating a relatively coarse texture with the abrasions concentric with the axis of rotation of the disk. Thereafter, the roughness of the texturing is reduced by abrading the surface of the disk with a polishing pad and an etchant slurry of colloidal silica. The etchant component has the property of attacking or softening the glass disk during the fine polishing with the colloidal silica slurry. As both the texturing step and the fine polishing step deposit a plurality of concentric abrasions on a glass disk, these abrasions aid in retaining the magnetically recordable coating deposited thereon to complete a magnetically recordable disk for use as a data storage member.
摘要翻译： 为磁性可记录涂层制备抛光玻璃盘，通过在盘旋转时与表面磨蚀性地接合的高度磨蚀的材料进行纹理化，从而产生相对粗糙的质地，其磨损与盘的旋转轴线同心 。 此后，通过用抛光垫和胶体二氧化硅的蚀刻剂浆料研磨盘的表面来减少纹理的粗糙度。 蚀刻剂组分在用胶体二氧化硅浆液进行精细抛光时具有攻击或软化玻璃盘的性质。 由于纹理化步骤和精细抛光步骤都在玻璃盘上沉积多个同心磨擦，所以这些磨损有助于保持沉积在其上的磁性可记录涂层以完成用作数据存储部件的磁性可记录盘。

摘要： A dressing disk for dressing and reconditioning the polishing pad of a planetary disk polishing machine is fabricated by plating a nickel/diamond matrix layer onto a stainless steel disk wherein the matrix layer thickness is developed or plated to a thickness which leaves exposed about 25 percent of the fine diamond particles, thereby forming a surface that has the look and feel of medium to coarse sandpaper. The dressing disks are inserted into the holes in a disk carrier of a planetary polishing machine and driven by its central rotary drive. While being so driven under a flow of water to carry away abraded particles, a pair of polishing pads are engaged with the disk surfaces and forced together with a loading or down force to cause the disks to abrade or grind away a thin surface layer of the polishing pad, thereby removing glazing and exposing cerium particles embedded in the urethane matrix of the polishing pad to engage the glass disks to be polished to a very smooth surface for use as substrates for magnetic memory disks useable in disk drives.
