Abstract
Surface profile of a magnetic recording medium and a magnetic recording head are rough when viewed on a microscale. When the head and the medium come in contact, the contact takes place at the top of the asperities. The real area of contact increases as the asperities of a particulate medium are deformed by a given head load. A larger real area of contact results in a higher real coefficient of friction. Estimation of the real area of contact in the head-medium interface is very important as the real area of contact needs to be minimized for decreasing the friction and wear.1) 2) This paper presents the experimental techniques for not only measuring topography of magnetic media when the medium is loaded, but also the influence that the size and the number of the asperity contacts have on the real area of contact.
