Method and apparatus of recording data on write-once recording medium
First Claim
1. A method of recording data on a recording medium having a lead-in area, a lead-out area, and a data zone, the data zone having a user data area and a spare area, the method comprising:
- recording first data in a first replacement area when a command for physically overwriting the first data in a first area within the user data area is received and the first area is included in a pre-recorded area;
recording a first entry in a temporary disc management area (TDMA), the first entry specifying locations of the first area and the first replacement area;
recording second data in a second replacement area when a command for recording the second data in a second area within the user data area is received and the second area is found to be defective; and
recording a second entry in the TDMA, the second entry specifying locations of the second area and the second replacement area.

Abstract
An apparatus of recording data on a recording medium includes an optical recording device and a microcomputer. The recording medium has a lead-in area, a lead-out area, and a data zone, where the data zone has a user data area and a spare area. When the microcomputer receives a command for physically overwriting first data in a first area within the user data area and determines that the first area is included in a pre-recorded area, it controls the recording device to record the first data in a first replacement area instead and to record a first entry in a TDMA, where the first entry specifies the locations of the first area and the first replacement area. In addition, when the microprocessor receives a command for recording second data in a second area within the user data area and finds the second area defective, it controls the optical recording device to record the second data in a second replacement area instead and to record a second entry in the TDMA, where the second entry specifies the locations of the second area and the second replacement area.

16. An apparatus of recording data on a recording medium having a lead-in area, a lead-out area, and a data zone, the data zone having a user data area and a spare area, the apparatus comprising:
-
an optical recording device configured to record data on the recording medium; and
a microcomputer providing control signals to the optical recording device to record first data in a first replacement area when a command for physically overwriting the first data in a first area within the user data area is received and the first area is included in a pre-recorded area, and to record a first entry in a temporary disc management area (TDMA), the first entry specifying locations of the first area and the first replacement area, wherein the microprocessor further provides control signals to the optical recording device to record second data in a second replacement area when a command for recording the second data in a second area within the user data area is received and the second area is found to be defective, and to record a second entry in the TDMA, the second entry specifying locations of the second area and the second replacement area. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
