Title: Disk controller configured to perform out of order execution of write operations

Abstract: A buffer memory controller comprises a first memory configured to buffer write operation data between a write head and a second memory that stores write operation data corresponding to first and second write operations. A first memory location identifies a location of write operation data that corresponds to the first write operation stored within the second memory. A second memory location identifies a location of write operation data that corresponds to the second write operation stored within the second memory. Controller logic determines whether the first write operation and the second write operation write data to the same track. The controller logic transfers the data of the first write operation and the second write operation in an order other than the order in which the second memory received the first and second write operations when the first write operation and the second write operation write data to the same track.
