Salient embodiments comprise magnetic recording sliders whose record-confronting face is characterized by two or three rails wherein stiction forces are counter-acted by provision of 'boss means' on one or several rails, or therebetween; and also characterized by provision of 'back-bar means' and associated purge channel means; and methods for rendering such are also described.

Slider for inhibiting stiction and with backbar

Slider for inhibiting stiction

Salient embodiments comprise a magnetic recording slider whose record-confronting face is characterized by two or three rails wherein stiction forces are counter-acted by provision of piezo-electric boss means on one or several rails, or therebetween.

Techniques for providing slider with boss

Methods for providing back bar and boss for slider

Salient embodiments comprise magnetic recording sliders whose record-confronting face is characterized by two or three rails wherein stiction forces are counter-acted by provision of a 'boss' on one or several rails, or therebetween; and also characterized by provision of a 'back-bar' and associated a purge channel; and methods for rendering such are also described.

Techique for providing back bar and boss for slider

A method of adapting a magnetic recording slider having a shallow 'flying cavity' on its media-confronting face to exhibit 'self-purging', better stability and increased stiffness, this method including: providing a back bar across the trailing face of the cavity, with a purge channel in the back-bar to purge the cavity of gas and associated contaminants.

Method of adapting slider to include back-bar

Salient embodiments comprise a magnetic recording slider whose record-confronting face is characterized by two or three rails wherein stiction forces are counteracted by provision of piezo-electric boss means on one or several rails, or therebetween.

Slider with boss

Slider with piezo-boss

Described are Delta-shaped magnetic recording 'sliders', some being provided with a 'back-bar' and associate 'purge channel', the air bearing surface area of the sliders increasing gradually from a minimum at its nose to a maximum at its trailing edge.
