Method of managing optimum power control data in lead-in zone of high-density optical disc
First Claim
1. A method of managing optimum power control (OPC) data in a lead-in zone of a high-density optical disc, comprising:
- allocating a specified zone used in performing an OPC process in the lead-in zone of the rewritable high-density optical disc; and
writing OPC data for the OPC process to the specified zone.

Abstract
A method of managing optimum power control (OPC) data in a lead-in zone of a rewritable high-density optical disc, wherein an OPC back data zone is allocated in the lead-in zone of the rewritable high-density optical disc and OPC data is written in the OPC back data zone so that a subsequent OPC process can be immediately performed based on the written OPC data. The method includes allocating a specified zone used in performing an OPC process within the lead-in zone of the rewritable high-density optical disc, writing OPC data for the OPC process in the specified zone, reading the OPC data written in the specified zone, and performing the OPC process based on the read OPC data.
