Claim 16:
17. A method comprising:
classifying, by a controller of a data storage device, data access operations to be carried out in the data storage device into primary data access operations and secondary data operations based on one or more data operation characteristics;
calculating, by the processor, at least one access trajectory from a first disc surface location to at least one second disc surface location at which at least one primary data access operation of the primary data access operations is to be carried out; and
determining, by the processor, whether an opportunity to commence at least one secondary data access operation of the secondary data access operations exists along or proximate to the at least one access trajectory from the first disc surface location to the at least one second disc surface location
in response to determining that the opportunity to commence the at least one secondary data access operation exists, commencing the at least one secondary data access operation; and
determining how much of the secondary data access operation to complete based at least in part on one or more performance constraints on the at least one primary data access operation or a group of data access operations including the at least one primary data access operation.
