Decoding policy management to support multiple decoding schemes in a single buffer space

A system comprising:

• a read/write channel configured to:
• select a first recovery scheme for a decoding attempt on a first subset of a set of failed data blocks read from a data track of a storage medium;
• select a second different recovery scheme for a decoding attempt on a second subset of the set of failed data blocks read from the data track;
• and
• during a single revolution of the storage medium, perform operations to decode a first subset of the failed data blocks according to the first recovery scheme and perform operations to decode the second subset of the failed data blocks according to the second different recovery scheme.

One or more computer-readable storage media encoding computer-executable instructions for executing a computer process comprising:

• selecting a first recovery scheme for a decoding attempt on a first subset of a set of failed data blocks read from a data track on a storage medium;
• selecting a second different recovery scheme for a decoding attempt on a second subset of the set of failed data blocks read from the data track;
• and
• during a single revolution of the storage medium, performing operations to decode a first subset of the failed data blocks according to the first recovery scheme and performing operations to decode the second subset of the failed data blocks according to the second different recovery scheme.
