Data recording apparatus with recording control based on defect block and control method thereof

A recording apparatus control method, comprising:

• a data recording step of recording data including first data and second data different from the first data onto a recording medium having a plurality of blocks including an alternative block for a defect block;
• an acquisition step of acquiring an alternative block remaining amount of recording medium;
• and
• a control step of selecting, in accordance with the alternative block remaining amount acquired at the acquisition step, data inhibited from being recorded in the recording medium among the first data and the second data and controlling the recording unit such that the selected data is inhibited from being recorded in the recording medium,
• wherein if the alternative block remaining amount acquired at the acquisition step is equal to or less than a threshold value, the control step selects the second data as the data inhibited from being recorded in the recording medium among the first data and the second data and controls the recording unit such that the first data is recorded in the recording medium and the second data is inhibited from being recorded in the recording medium.

A data recording apparatus comprising:

• a recording unit configured to record a plurality of types of information data on a recording medium having a plurality of blocks including an alternative block for a defect block;
• an acquisition unit configured to acquire an alternative block remaining amount of the recording medium;
• and
• a control unit configured to designate, in accordance with an alternative block remaining amount in the recording medium acquired by the acquisition unit, a type of data inhibited from being recorded among the plurality of types and to control the recording unit such that data of the designated type is inhibited from being recorded in the recording medium,
• wherein if the alternative block remaining amount is equal to or less than the threshold value, the control unit designates a predetermined type as the type of the data inhibited from being recorded and controls the recording unit such that data of a type different from the predetermined type is recorded in the recording medium and data of the designated type is inhibited from being recorded in the recording medium.
