First Claim
Patent Images
1. A controller for a disk drive, the controller comprising:
- first memory that stores first write operations and second write operations that are received in a first order;
a processor that arranges the first write operations and the second write operations in a second order based on respective track sectors associated with the first and the second write operations, the second order being different from the first order; and
a memory controller that transfers write operation data corresponding to the first write operations and the second write operations to a disk formatter in the second order in response to a single command from the processor.

Abstract
A controller for a disk drive includes first memory storing first write operations and second write operations received in a first order. A processor arranges the first write operations and the second write operations in a second order based on respective track sectors associated with the first and the second write operations. The second order is different than the first order. A memory controller transfers write operation data corresponding to the first write operations and the second write operations to a disk formatter in the second order in response to a single command from the processor.

10. A method for operating a controller of a disk drive, the method comprising:
-
storing first write operations and second write operations in a first memory, the first write operations and second write operations having been previously received in a first order; using a processor to arrange the first write operations and the second write operations in a second order based on respective track sectors associated with the first write operations and the second write operations, the second order being different from the first order; and in response to a single command from the processor, transferring write operation data corresponding to the first write operations and the second write operations to a disk formatter in the second order. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
