Proximity recording" terminology has been used for the head/media system with the head jlying close to the media surface. With current media technology, the glide avalanche is about 1 pin ; a head which flies at less than 2 pin has been considered to be in the proximity regime. To date there has been little amounts of literature or study on this subject. This paper proposes a new regime of the head/media interface that the proximity recording technology is based upon. It is called the pseudo contact regime. This paper will present new considerations in the designs of airbearing and suspensions for the proximity recording head as well as additional tribological issues. IntroductionIn magnetic recording the most effective way to gain higher areal density has been to reduce spacing loss. Flying height is one of the largest contributors, hence there is a large body of literature and much research focused on this topic. Engineers in the magnetic recording industry have been able to bring the flying height down from 10 pin to 2 pin in a ten year period. This accomplishent is credited both to the airbearing designers and the tribologists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
