Managing data associated with overwritten portions of previously-written tracks

A data storage device comprising:

• a data storage medium having a data storage surface;
• a head configured to interact with the data storage medium;
• a controller communicatively coupled to the head, the controller configured to:
• direct the head to write first data on a first track of the data storage surface;
• store information for the first data in a memory other than the data storage surface;
• direct the head to perform a write operation on a second track of the data storage surface after the data is written on the first track, the second track being adjacent to the first track;
• identify potentially-overwritten sectors of the first track as a result of the performance of the write operation on the second track;
• perform a first read operation on the identified potentially-overwritten sectors of the first track after completion of the write operation on the second track;
• and
• store second data associated with the identified potentially-overwritten sectors in a solid-state memory.

A method comprising:

• writing first data on a first track of a data storage surface;
• storing information for the first data in a memory other than the data storage surface;
• performing a write operation on a second track of the data storage surface after the data is written on the first track, the second track being adjacent to the first track;
• identifying potentially-overwritten sectors of the first track as a result of the performance of the write operation on the second track;
• performing one or more read operations on each of the identified potentially-overwritten sectors of the first track after completion of the write operation on the second track;
• and
• storing second data associated with every sector of the identified potentially-overwritten sectors whose data is unrecoverable after a predetermined number of read operations in a solid-state memory.
