US 11,610,603 B2 · Intelligent region utilization in a data storage device

Abstract

A data storage device can have one or more rotating data media with data tracks that are radially disposed from a central spindle. The data tracks may be logically divided into multiple regions while a write strategy is generated with a region module to set a sequence of different regions for future data writes. Receipt of a data write request to the data storage media from a host can prompt the region module to classify the data write request as a sequential or random write in order to intelligently select a region to satisfy the data write request based on the write strategy to maximize data writing consistency for data associated with the data write request.

Dependent claims

A method comprising:

dividing a surface of a data storage medium into logical regions by a region module;
positioning a transducing head to access data on the surface;
generating a region strategy with the region module, the region strategy prescribing a transducing head progression sequence between regions to balance data transfer time with seek time during satisfaction of a pending write request to increase input output throughput per second (IOPS) consistency, region strategy prescribing moving the transducing head from an inner diameter of the surface directly to an outer diameter of the surface in accordance with the transducing head progression sequence;
and
executing the region strategy in response to a write request to satisfy the write request with an IOPS consistency below a predetermined threshold.
