PROBLEM TO BE SOLVED: To provide a disc device capable of improving the hit efficiency in a cache buffer to a read request from a host device by looking only estimated data ahead and storing them in the cache buffer even in the receipt of a skip read request from the host device, and a cache control method for this device. SOLUTION: The cache control method for this disc device comprises judging whether the read request from the host device is the skip request or not from the address information stored in an address storage means, calculating a skip address that is the address to be read next by the skip request when the skip request is judged, and selecting the information for the area designated by this skip address to execute a skip cache.
