1. the optical disc apparatus of a recorded information on CD, described CD has:

  • Wherein the data field of user data (103),Be arranged on inboard first Lead-In Area (102) in data field (103) andBe arranged on second Lead-In Area (104,105) in the outside, data field (103),Wherein, first Lead-In Area (102) comprising;

    first learning region (201), and it is the operation setting optimal conditions of record data in the data field;

    With management information recording areas (202), the user data that its management is write down in the data field,Second Lead-In Area (104,105) comprising;

    protected location (104), and it protects the user data of side part within it;

    With second learning region (105);

    it is arranged on the outside, protected location (104); and

    be the operation setting optimal conditions of record data in the data field, the wherein zone of the information of the using method of record indication protected location (104) is provided in management information recording areas (202), andDescribed device has pick-up head (501), prime amplifier (502), signal processing circuit (503) and controller (505), wherein pick-up head (501) and prime amplifier (502) obtain reproducing signal from CD, signal processing circuit (503) extract management information from reproducing signal, controller is handled management informationDescribed optical disc apparatus is characterised in that and comprises;

    Obtain the device (SA1, SA2) of the residual capacity of data field and learning region,Determine the device (SA3) of the residual capacity of learning region,If the residual capacity of learning region surpasses the capacity that presets, then in learning region, carry out normal learning manipulation, and finish the device (SA4) of learning manipulation,If the residual capacity of learning region surpasses the capacity that presets, the device of the residual capacity in specified data district (SA5) then,If the residual capacity specific storage B1 of data field is little or littler than presetting capacity, then in the learning region remainder, carry out learning manipulation, and finish the device (SA5-SA4) of learning manipulation,If the residual capacity exceed capacity B1 of data field or preset capacity then except that the learning region remainder, carries out the device (SA6) of learning manipulation in the protected location,Record is used in reference to be shown and determines described optimal conditions and as the device (SA7) of the information of the protected location of learning region in the management information recording areas.
