A photopolymerization sensitizer may not cause problems of dusting or coloring of a cured product due to bleeding of additives such as the photopolymerization sensitizer on the surface, e.g., by blooming at the time of photo-curing or during storage of the cured product, and which provides a practically sufficient photo-curing rate. A 9,10-bis(alkoxycarbonylalkyleneoxy)anthracene compound having ester groups, of formula (I): wherein A is a Calkylene group, optionally branched by an alkyl group, R is a Calkyl group, optionally branched by the alkyl group, the Calkyl group optionally being a cycloalkyl group or a cycloalkylalkyl group, and X and Y are independently a hydrogen, a Calkyl group, or a halogen.

Migration-resistant photopolymerization sensitizer

A end report of the unloading operation is issue to a host computer for a period of time after the start of the ejecting operation of a medium cartridge of a recording/reproducing unit based on an unloading command until before the end of the unloading operation, thereby allowing the next moving command to be issued precedently to the end of the actual unloading operation. Simultaneously there for with that the unloading operation is instructed to the recording/reproducing unit on the basis of the unloading command, the end report of the unloading operation is executed to the host computer, thereby allowing the host computer to issue the next moving command. In a data transfer control between the host computer and a control unit of a library apparatus, when the number of error times of the data transfer errors exceeds a threshold value, the subsequent data transfer speed is switched to the executable data transfer speed at which the data transfer can be retried, and the data transfer is executed.
