Abstract
An information readout apparatus reduces an effective wait time and shortens access time when information recorded on a magnetic disc is read out by effectively utilizing a wait time of a disc rotation. When a sector on the magnetic disc on which a magnetic head is currently positioned is between a start address and an end address, information behind the current sector is buffered and the sequence of the buffered information is rearranged as required and read out so that overlapped readout of the previously read information from the magnetic disc is prevented to shorten the access time. The current sector address is compared with the start address and the end address to process the information.
