Abstract
This invention provides for increasing useful data area on a zone-textured disc. The disc drive device has at least one disc having a CSS zone and a data zone with a plurality of concentric tracks on the disc surface. The contact start/stop zone of the disc surface is where the slider takes off from and lands on the disc surface. Each track includes at least one data segment capable of storing data. A transducer writes data to and reads data from the concentric tracks on the surface of the disc. The transducer is connected to a slider which has an air bearing surface (ABS) with an inner side and an outer side. In the present invention, the fly height of the inner side of the ABS is greater than a fly height of the outer side of the ABS in the area of the data zone nearest to the CSS zone. Offsetting the fly height of the inner side of the ABS to be greater than the fly height of the outer side of the ABS allows the slider to move slightly from the CSS zone to the data zone so that a portion of the ABS containing the transducer is over the data zone nearest to the CSS zone.
