Abstract: A disc driving apparatus includes: a recording and reproducing unit for recording or reproducing an information signal; and a print unit for performing printing to the printing surface of the disc-shaped recording medium. The print unit includes a print head contacting the printing surface when performing printing, a head feeding unit having a head support lever to which the print head is mounted, a guide cam having a cam guide portion extending in a movement direction of the head feeding unit, a moving cam having an forward path cam engagement portion engaged with the cam guide portion in the forward path and a return path cam engagement portion engaged with the cam guide portion in the return path; and a guide member guiding the movement of the head feeding unit between the initial location and the turnaround location.

Abstract: A disc driving apparatus includes a recording and reproducing unit for recording or reproducing an information signal for a disc-shaped recording medium having a printing surface and a print unit for performing printing to the printing surface of the disc-shaped recording medium. The print unit includes a print head which is pressed to the printing surface when printing is performed on the printing surface, a head feeding unit to which the print head is mounted, the head feeding unit moving along the printing surface of the disc-shaped recording medium, and a guide member for guiding the movement of the head feeding unit. When the print head is pressed to the printing surface while printing is performed on the printing surface, the disc-shaped recording medium is bent so that the printing surface becomes inclined. The guide member is disposed to be inclined according to the inclined state of the printing surface.

Abstract: The reuse of an ink ribbon is prevented and the image quality and the proper paper feeding operation are secured by providing an ink ribbon damaging means to a ink ribbon cartridge of a color video printer. For example, a ring cutter is provided to the spool shaft of a spool on which an ink ribbon used for printing is wound so that the ink ribbon wound on the spool is cut.
