Abstract: In a method, a first area and a second area of a current frame is determined when the current frame is a GDR frame. The first area is independently coded and the second area is coded with dependency. When a current block in the current frame is coded by an intraTMP mode or an IBC mode, a search range of the intraTMP mode or the IBC mode is determined such that the search range is only in the first area of the current frame. A reference block is determined from a plurality of candidate reference blocks in the search range. The current block is encoded in a bitstream based on the determined reference block.

Abstract: A method of manufacturing hard disk drives (HDDs) includes assembling a first HDD including a first slider having a first air bearing surface (ABS) configuration, configuring the first HDD to rotate its disk media at a first revolutions-per-minute (RPM), and sealing the first HDD with a first internal pressure level. Continuing, the method includes assembling a second HDD including a second head slider having the same first ABS configuration, configuring the second HDD to rotate its disk media at a second RPM that is lower than the first RPM, and sealing the second HDD with a second internal pressure level that is higher than the first pressure level. Thus, in the context of using a common slider among different RPM drives, a higher internal pressure for the lower RPM drive can compensate for loss in fly height that might otherwise occur due to the lower operational RPM.
