Abstract
This disclosure deals with the management of data in the memory of a digital media playback device. Specifically this dislcosure deals with the mechanisms to allow memory to be treated as a partitioned resource, regardless of the physical implementation of the data storage in the playback device. Manage the memory on a digital media player as logical partitions, not just physical partitions between different types of memory. This will treat the entire memory space as a uniform piece of memory, regardless of whether the memory is internal memory with battery backup, Flash memory that behaves like a logical disk, rotating media that is read/write (typically magnetic disk or CD-RW or DVD-RW) or rotating media that is read only. Overlaid on this uniform memory model is a partitioned memory model that divides the memory into logical devices that are used to constrain the size of the memory used for various (logical) types of digital media.
