Ultrasonic polishing of giant magnetic resistance magnetic recording heads for hard discs
Abstract The material removal rate (MRR) is very low and it is difficult to achieve a pole tip recession (PTR) smaller than 10 nm with conventional polishing. Ultrasonics was applied to the recording head polishing with a float-piece polisher to find a new method to reduce the PTR and increase the MRR. The power of ultrasonics used in the experiment was 35 W, and its frequency was 40 kHz. Two pieces of rowbars were fixed on the specimen holder, and the rotational speed of the plate was 25 r/min. The MRR and the roughness of the surface were improved, and the PTR was reduced to 1-2 nm.
期刊介绍:
The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications.
"I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there." Professor Rob Dwyer-Joyce, Sheffield University, UK
