Abstract
An information medium apparatus for performing at least one of a recording operation and a reproduction operation for the information medium, includes: a determination section for determining whether or not a cartridge for accommodating the information medium has been previously opened; and a control section for performing a start processing procedure corresponding to the information medium. When it is determined that the cartridge has not been previously opened, the control section performs a first start processing procedure for starting the information medium by using a blue laser. When it is determined that the cartridge has been previously opened, the control section determines whether or not the information medium is an information medium for which a start processing procedure is to be performed by using a laser other than the blue laser.
