Enhanced capacity recording

摘要

A storage device includes a storage controller configured to write a band of data tracks using a first recording method until criterion is met. The first method may be a conventional recording method. After the criterion is met, the storage controller is configured to write data to the band using a second recording method. The second recording method may be an enhanced capacity recording method such as interlaced magnetic recording (IMR) or shingled magnetic recording (SMR).

1. A storage device, comprising:
a storage media; and a storage device controller configured to:
write data to one or more data tracks of a target band on the storage media using a first recording scheme,monitor the target band to determine whether a criterion has been satisfied;read the one or more data tracks of the target band into a memory met responsive to a determination that the criterion has been satisfied; andwrite the one or more data tracks to the target band on the storage media using a second recording scheme different from the first recording scheme.
