Abstract

A recording medium driving device includes a recording and/or playback unit for performing at least one of recording of a data signal on the recoding surface of a recording medium, and playback of a data signal from the recording surface, a printing unit for printing visible information on the main surface different from the recording surface of the recording medium using an inkjet method, a driver for performing driving as to the recording medium, and a drive control unit for switching the driving speed of the driver by a printing mode for printing visible information on the main surface or a recording/playback mode for recording or playback of the data signal on/from the recording surface.

Claims

1. A recording medium driving device comprising:

a recording and/or playback unit for performing at least one of recording of a data signal on the recoding surface of a recording medium, and playback of a data signal from said recording surface;

a printing unit for printing visible information on the main surface different from said recording surface of said recording medium using an inkjet method;

a driver for performing driving as to said recording medium; and

a drive control unit for switching the driving speed of said driver by a printing mode for printing visible information on said main surface or a recording/playback mode for recording or playback of said data signal on/from said recording surface.

2. The recording medium driving device according to claim 1, wherein the driving speed of said printing mode is slower than the driving speed of said recording/playback mode.

3. The recording medium driving device according to claim 1, wherein said printing unit adjusts a printing position based on the positional information of said recording medium read out from a reference signal recorded on the recording surface of said recording medium.

4. The recording medium driving device according to claim 3, wherein said reference signal is recorded on the circumference in one or a plurality of predetermined radius distance of said recording medium.

5. The recording medium driving device according to claim 1, wherein said printing unit adjusts the number of times of ink discharge per unit time depending on the radius distance from the center of said recording medium of the printing position of said visible information.

6. A recording medium driving method employing a recording medium device including

a recording and/or playback unit for performing at least one of recording of a data signal on the recoding surface of a recording medium, and playback of a data signal from said recording surface, and

a printing unit for printing visible information on the main surface different from said recording surface of said recording medium using an inkjet method, for printing said visible information,

said method comprising the step of:

switching the driving speed of a driver for driving said recording medium by a printing mode for printing visible information on said main surface or a recording/playback mode for recording or playback of said data signal on/from said recording surface.
