摘要:
Derivatives of .alpha.,.alpha.-trehalose-6,6'-fatty acid diester having phosphoric ester groups in the molecule which are useful as a carcinostatic agent. One of the derivatives may be prepared by reacting diphenylphosphoryl chloridate with a derivative of 2,3,2',3'-tetra-O-benzyl-.alpha.,.alpha.-trehalose-6,6'-fatty acid diester. Another derivative may be obtained by substituting benzyl groups at 2,3,2',3' positions of trehalose with hydrogen atoms.

摘要:
When an external recording medium connected to an interface is removed therefrom and a new external recording medium is connected to the interface, a processor selects either first file analysis information read from a memory or second file analysis information generated based on analysis of data recorded on the new external recording medium as file analysis information to be used for decoding a file stored in the new external recording medium, and the processor makes such selection based on comparison between first recording medium management information and second recording medium management information.
