An erase prohibition setting unit sets erase prohibition in accordance with an instruction. When the range is not set in units of cells of the current cell, the current cell is divided by a cell separator to set a sequence of advanced cells. A reconstruction part reconstructs management information for playing, back the advanced cells and current cell, and appends erase prohibition information to the management information for playing back the advanced cells that belong to the range.
