Abstract
An improved head assembly having air bearing features for contaminant control in flexible media high contact-pressure zone. The head assembly having one or more air bearing features for improving the performance of the heads by controlling a flow of contaminants away from the head sensor and the high contact-pressure zone. The improved head assembly having air bearing features allows the head to keep contaminants out of the high contact-pressure zone proximate the head disk interface where the sensor communicates (e.g., contacts) the flexible media. The head assembly of the present invention includes a shaped slot air bearing feature formed in the rail having the sensor that directs the flow of contaminants away from the high contact-pressure zone and therefore, away from the sensor. This helps to prevent problems associated with head spacing and also damage to the head, the disk, and/or both. In addition, the present invention can also include an additional shaped slot air bearing feature positioned by the sensor. In another embodiment of the present invention, the head assembly has a shaped rail air bearing feature for controlling a flow of contaminants from entering the high con…
