Abstract
A controller and a method for interfacing with a storage medium. Access to a buffer memory via a multi-channel bus is arbitrated. DWFT (Data Wedge Format Table) entries stored in the buffer memory are read and cached in a DWFT cache memory. Data is transferred to and from the storage medium through a storage medium interface. The storage medium interface accesses the sectors of the storage medium based on their physical locations, as defined by the cached DWFT entries. The multi-channel bus includes a DWFT channel to which DWFT cache circuitry is connected. In a DWFT tenure, the DWFT cache circuitry reads the DWFT entries stored in the buffer memory, and caches the DWFT entries in the DWFT cache memory.
