PROBLEM TO BE SOLVED: To provide a technique for improving command queue rearranging process with the load of processor resource decreased. SOLUTION: This invention provides a hardware command queue with a memory device for a mass memory system. Plural entries are demarcated within the memory device, at least several among which are active entries. Among the active entries, at lease several are associated with pending access commands with at least one entry as a head entry associated with the active command in operation. Physical target position is stored in each active entry with the calculated servo distance stored in each active entry. A link list including a pointer for defining execution sequence is stored together with the command queue.
