Hard disk drive progressive channel interface. A novel approach is presented by which the interface between a channel circuitry and a controller circuitry, such as those which can be implemented within a hard disk drive (HDD). Because of the location in which the disk management operations are supported and performed within the channel circuitry, the interface between the channel circuitry and the controller circuitry can be implemented to support direct memory access (DMA) protocol data transfers and control there between. Because the disk management operations are supported within the channel circuitry, as opposed to the controller circuitry, then the disk management operations need not necessarily comply with an interface between the channel circuitry and the controller circuitry. This allows for better control of the disk management operations as well as a much broader range and type of interface that can be employed for the interface between the two circuitries.
