Abstract

A method for processing requests for information from a disc drive comprising: (a) receiving a plurality of requests, wherein each of the requests has application level information associated with it; (b) identifying a first group of the requests that fit within a time interval; (c) using a scheduling algorithm with disc information to schedule one of the requests in the first group; (d) adjusting the length of the time interval; (e) identifying another group of the requests that fit within the adjusted time interval; (f) using the scheduling algorithm to schedule one of the requests in the other group; and (g) repeating steps (d), (e) and (f). An apparatus that processes requests for information in accordance with the method is also provided.
