DATA TRANSFER SCHEME FOR EFFICIENTLY MOVING DATA THROUGH A HIGH LATENCY MEDIA ACCESS CHANNEL

A non-volatile storage subsystem comprises a media I/O controller, a media access channel, and movable storage media. A non-volatile disk storage subsystem bas a read channel coupling a disk controller to a disk head assembly. A read channel interfacing subsystem is provided as part of the storage subsystem, and the read channel interfacing subsystem interfaces a disk controller to the read channel. The read channel interfacing subsystem comprises a set of process units and a pipeline manager.
