This Small Business Innovation Research (SBIR) Phase II project will develop novel, water soluble, environmentally benign, aspartate co-aspartamide copolymers for use as aluminum titanium carbide (AlTiC) Giant Magnetoresistive (GMR) Read Write Head lapping fluid additives. Efforts will be directed towards refining the composition of these copolymers such that they exhibit maximum adsorption & electrostatic charging effects upon AlTiC surfaces. This will enable rapid removal of AlTiC swarf formed during lapping producing GMR Heads of superior surface quality and uniformity compared to those manufactured currently. Furthermore, the adsorption properties of these copolymers upon AlTiC ceramic GMR Head surfaces as well as their metallic sensor layers will also be characterized in greater detail using Zeta Potential & Electrochemical Techniques. An optimized procedure for synthesizing these copolymers will be established enabling them to be economically produced in bulk quantities. Finally, the company will work closely with hard drive manufacturers and will integrate the aqueous lapping fluids formulated from these copolymers into its current GMR Head manufacturing operations. Commercially and from an industrial standpoint, lapping fluids formulated from these copolymers will enable the last vertically integrated domestic hard drive manufacturer to produce GMR Read Write Heads more economically & efficiently thereby enhancing the company's competitiveness within the marketplace. Future data storage technologies may also benefit from these fluids since they will in all likelihood still require high precision lapping or a related super finishing technique to polish their drive components.

这项小型企业创新研究（SBIR）II期项目将开发新颖，水溶性，环境良性，天冬氨酸共胺共聚物，用作碳化铝钛（Altic）巨型磁层（GMR）读取头部贴头盖添加剂。 努力将用于完善这些共聚物的组成，以使它们对海拔表面表现出最大的吸附和静电充电效应。 这将使与当前制造的质量相比，在收盘产生产生优质表面质量和均匀性的GMR头部时形成的高度SWARF的快速去除。 此外，这些共聚物在高度陶瓷GMR头表面以及其金属传感器层上的吸附性能也将使用Zeta电位和电化学技术更详细地进行表征。 将建立一种合成这些共聚物的优化程序，使它们能够大量经济生产。最后，该公司将与硬盘驱动器制造商紧密合作，并将从这些共聚物配制的水性结合流体集成到当前的GMR头制造运营中。 从商业上讲，从工业的角度来看，这些共聚物制定的液体将使最后一个垂直整合的国内硬盘驱动器制造商能够更经济，有效地生产GMR读写，从而增强了公司在市场上的竞争力。 未来的数据存储技术也可能会从这些流体中受益，因为它们很可能仍然需要高精度的打击或相关的超级精加工技术来抛光其驱动器组件。
