Abstract
A modified read-ahead (i.e., jump) command, contains a sequential access parameter SAP, JUMPm(X,Y:SAP), for instructing a disc drive to jump to block Y after having read block X. If the SAP parameter has a value indicating that a host, such as a PC, designed to recognize the SAP parameter, deliberately signals a disc drive to jump to a lower address (e.g., Y<X), a disc drive designed in accordance with the present invention will comply. A disc drive not designed to recognize the modified read-ahead command may ignore the SAP parameter. A host not designed to recognize the modified read-ahead command is not capable of setting the SAP parameter.
