Information storage medium and method and apparatus for recording/reproducing data on/from the same

An apparatus for recording/reproducing data on/from a recordable information storage medium including a plurality of recording layers, the apparatus comprising:

• a pickup that irradiates a beam onto the information storage medium;
• a recording/reproducing signal processor that receives a beam reflected from the information storage medium through the pickup for signal processing;
• and
• a controller that controls the pickup to record data in the order of recording layers from closest to farthest from the pickup and not to record data on predetermined regions located on inner and outer circumferences of a user data area of the recording layer on which data is being recorded except the recording layer closest to the pickup.

An apparatus for recording/reproducing data on/from a recordable information storage medium including a plurality of recording layers, each recording layer having an optimum power control (OPC) area for performing a test in order to determine optimum recording power, the apparatus comprising:

• a pickup that irradiates a beam onto the information storage medium;
• a recording/reproducing signal processor that receives a beam reflected from the information storage medium through the pickup for signal processing;
• and
• a controller that controls the pickup to record data in the order of the recording layers from closest to farthest from the pickup and not to record data on predetermined regions located on inner and outer circumferences of the OPC area of a recording layer on which data is being recorded except a recording layer closest to the pickup.

An apparatus for recording/reproducing data on/from a recordable information storage medium including a plurality of recording layers, the apparatus comprising:

• a pickup that irradiates a beam onto the information storage medium;
• a recording/reproducing signal processor that receives a beam reflected from the information storage medium through the pickup for signal processing;
• and
• a controller that controls the pickup to record data in the order of recording layers from closest to farthest from the pickup so that the size of a recorded region decreases according to a distance of a respective recording layer from the pickup.

A recordable optical disk having a plurality of recording layers, each layer comprising:

• a user recordable area;
• and
• an optimum power control (OPC) area for performing a test in order to determine optimum recording power, wherein:
• the OPC area of an inwardly disposed one of the plurality of recording layers is greater than the OPC area of an outwardly disposed one of the plurality of recording layers.

An apparatus for recording data on a recordable optical disk having a plurality of recording layers, the apparatus comprising:

• an optical pickup comprising an objective lens which irradiates a light beam onto the recordable optical disk;
• and
• a controller which assigns an optimum power control (OPC) area for each recording layer, the OPC area for performing a test to determine optimum recording power to a respective layer,
• wherein the controller assigns the OPC area of an inwardly disposed one of the plurality of recording layers a greater area than the OPC area of an outwardly disposed one of the plurality of recording layers.
