Write management of physically coupled storage areas
First Claim
1. A method comprising:
- transmitting read/write characteristics of a logical block address space, the read/write characteristics including coupling information characterizing a physical arrangement of data blocks associated with different logical zones in the logical block address space; and
executing a write command instructing a data write to a target logical zone of the logical zones, the write command generated based on the transmitted coupling information.

Abstract
A method for managing data bands within an interlaced magnetic recording (IMR) architecture includes transmitting read/write characteristics of a logical block address space, the read/write characteristics including coupling information characterizing a physical arrangement of data blocks associated with different logical zones in the logical block address space, where each of the logical zones spans a continuous range of logical block addresses mapped to a series of data blocks physically interlaced with another series of data blocks corresponding to another one of the logical zones. The method further provides for executing a write command instructing a data write to a target logical zone of the logical zones, the write command being generated based on the transmitted coupling information.
