  • Publication number: 20080019250
    Abstract: Disclosed herein is an information recording/reproducing apparatus that includes a first and a second recording/reproducing modules, a buffer memory to store information temporally, and a control module that switches between a first mode and a second mode when the information is dubbed from the first recording/reproducing module to the second recording/reproducing module. In the first mode, information in the first recording/reproducing module is reproduced and stored in the buffer memory. In the second mode, the information stored in the buffer memory is recorded in the second recording/reproducing module. The apparatus further includes a temperature detecting module. Depending on the temperature detected by this module, the apparatus changes the movement of the second recording/reproducing module in the first mode and the movement of the first recording/reproducing module in the second mode.

  • Publication number: 20070122114
    Abstract: In a recording apparatus equipped with a drive apparatus for recording data on a recording medium such as an optical disk, and a function capable of initializing a management information area of the recording medium, a storage unit is further provided. The storage unit stores thereinto initializing data which is used to be recorded on the management information area of the recording medium when the recording medium is initialized. In the case that an initializing operation is instructed, the recording apparatus records the initializing data which has been stored in the storage unit on the management information area of the recording medium from a beginning area thereof. Thus, a user no longer waits to use the recording medium until the initializing operation is accomplished when such a recording medium as a new optical disk is used, resulting in an improvement of user operability.
