Abstract
A system and method is described that allows random write operations regions utilizing shingled magnetic recording. The method includes receiving a request to re-write a logical block address (LBA) with new data, wherein the LBA is mapped to a physical block address (PBA) on a storage medium. The method further includes determining whether the data is eligible for a write-in place update wherein the data is written to an area of the I-region that has previously been written with shingled data tracks, wherein the eligibility determination is based on a mapping list of LBAs to PBAs. The method also includes writing the new data to the area of the I-region determined to be eligible for a write-in place update, wherein writing the new data further includes writing management information to the I-region that identifies a starting LBA of the write-in place update, and a length of the write-in place update.
