Abstract
The present invention relates to methods and systems for efficiently accessing data stored on a data storage device. The data storage device may comprise various types of media, such as shingled media and non-shingled media, alone or in combination. The data storage device may employ a logical block address space for specifying location of blocks of data stored on the data storage device. In addition, pre-determined sequential ranges of logical block addresses are grouped together and may be referenced collectively. In some embodiments, each type of media type may be partitioned into sections for containing different sizes of collections. Each collection of logical block addresses may be allocated to an arbitrary logical slot. Each logical slot may then be linked to a physical slot on the data storage device.
