1. A method comprising:
- writing data to a first series of data tracks within a region of a storage medium while a post-write scan operation is disabled and until a first capacity condition is satisfied, the data tracks of the first series each separated from one another by at least one interlaced data track; and
once the first capacity condition is satisfied, enabling a post-write scan operation to verify integrity of adjacent track data after a subsequent write operation.

Abstract
A storage device includes a controller that directs incoming data to a storage location based on a capacity of a region or surface of a magnetic disc. According to one implementation, the storage device controller writes new data to data tracks in a first series of data tracks on the magnetic disc until a capacity condition is satisfied. Once the capacity condition is satisfied, the storage device controller writes new data to a second series of data tracks on the storage medium that are interlaced with data tracks of the first series.
