ABSTRACT:
An information storage apparatus characterized in that provided with: a data writing unit that writes the data in a data-storable information recording medium; a control information writing unit that writes control information in a predetermined region of the information recording medium, the control information being related to the data-writing by said data writing unit; and a conditional control information writing unit that, while the data writing unit is writing the data in the information recording medium, if a predetermined condition is satisfied, writes the control information in the predetermined region of the information recording medium, the control information being related to the data-writing for the meantime by the data writing unit. If the predetermined condition is satisfied, the control information is written in the predetermined region of the information recording medium. Even if the power fails unexpectedly due to a power failure, for example, the loss of written data can be limited to a minimal extent.
