Abstract
A hard disk controller (HDC) of a hard disk drive (HDD) includes an encoder module, a buffer manager module, N first-in first-out (FIFO) modules, and N read channel modules, where N is an integer greater than 1. The encoder module is configured to encode data received from a host and to generate P units of encoded data, where P is an integer greater than 1. The buffer manager module is configured to store the P units of encoded data in a buffer, retrieve N of the P units from the buffer, and output the N units in parallel. The N FIFO modules are configured to receive the N units in parallel from the buffer manager. The N read channel modules are configured to receive the N units from the N FIFO modules in parallel, respectively, and to output the N units to a magnetic medium of the HDD.
