    • PURPOSE: To prevent interruption of recoding/reproducing of a information signal due to reproducing/reproducing of subinformation, by providing a subinformation recording medium recording subinformation and sub-recording/ reproducing means recording and reproducing subinformation.
      CONSTITUTION: An information carrier 1 has a main information recording medium (optical disc) recording an information signal and the subinformation recording medium (non-volatile semiconductor memory) recording a subinformation including information with regard to a main information recording medium or the like, and a control means 6 executes recording and reproducing at high speed by a sub-recording/reproducing means 4 to the subinformation recording medium in all information carrier 1 of a stocker 2. The control means 6 controls a carriage means 5 and a main recording/reproducing means 3 according to the subinformation and starts reproducing or recording of the information signal searching automatically an objective information carrier 1 from the stocker 2 in order. Since the subinformation recording/reproducing and the information signal recording/reproducing are independent each other, the information signal recording/reproducing is not interrupted.
