Abstract
Abstract An optical recording apparatus employing a method of halting a recording operation halfway a unitary frame of additional information and capable of realizing an exact operation in recording the additional information at the joint of preceding and present record portions. Out of the last unitary frame of the additional information in the preceding operation, the remaining information portion not included in the preceding record is generated, at the beginning of an additional recording mode, by an address information generator 4 from the content stored in an address information memory 6. And at the restart of recording the additional information, the recording operation is so performed that the remaining portion of the preceding last unitary frame of the additional information generated by the address information generator 4 is recorded in succession to the preceding record portion
