An information recording apparatus is capable of recording data and management information of an information recording medium in a plurality of data recording formats. A bonding material is used for internal bonding of the semiconductor device. Use of the data structure provides users with an easy-to-use interface. A controller coupled to the elevator and the obstruction detector may automatically cause the elevator to position the camera head in the up position when the obstruction detector determines that the field of view of the camera head in the down position is obstructed.
