Abstract

　記憶装置は、ヘッドを記憶媒体の任意の位置に位置決めする位置決めしてデータを記録又は再生する記録再生部と、パラメータ格納領域を割り当てた不揮発メモリを備える。調整部は位置決め制御部及び記録再生部の制御に必要な各種のパラメータを調整する。パラメータセーブ処理部は、調整部で得られた調整済みパラメータを、調整中は不揮発メモリにセーブし、パラメータ調整を終了した時点で記憶媒体のシステム領域のアクセスに必要な最小限の調整済みパラメータを残し、残りの調整済みパラメータは記憶媒体のシステム領域にセーブし、不揮発メモリのパラメータ格納領域に空き領域を形成する。空き領域処理部は、不揮発メモリの空き領域をファームウェアやログ等のパラメータ以外の格納領域に使用する。
