Abstract
Redundant Array of Inexpensive Platters (RAIP) uses data management and storage techniques and concepts from Redundant Array of Independent Disks (RAID) technology. These techniques and concepts that are used with multiple disks are incorporated into being used within a single disk drive. RAIP is used within a single disk drive having at least one platter and multiple heads. The at least one platter is utilized in the same or similar manner as at least one of the multiple disks in a redundant array of independent disks (RAID). RAIP is generally implemented by using each side of a platter of the single disk drive in the same or similar manner as each disk drive of multiple disk drives. A system and method of providing and implementing RAIP within a single disk drive is disclosed. The single disk drive is provided with at least one platter, a number of stripes located in the at least one platter for dividing storage within the at least one platter, and a number of heads communicatively coupled to the at least one platter for writing and reading data thereat. The data is stored in the at least one platter in a redundant array level, and the stripes in the at least one platter are used…
