Abstract
An information recording device includes a recording medium with a plurality of data tracks and a controller that stores management information regarding data recorded in a group of adjacent data tracks, the recorded data including first data recorded in a first data track that is partially overwritten by second data subsequently recorded in a second data track that is adjacent to the first data track. The controller recovers management data of the recorded data based on whether or not a sector in the first data track that is adjacent to a sector in the second data track can be read by offset read processing when the sector in the second data track cannot be read by normal read processing.
