Method and the device which form the optimum record power proofreading territory on the entry possible multilayer optical recording carrier, and this kind of optical recording carrier which possess the optimum record power proofreading territory

摘要

The plural record layers L_{0 which} are separated by the spacer material,...Being the entry possible optical recording carrier (100) which possesses L _n-1, each record layer has the optimum record power proofreading territory (101,111,121,131), this optimum record power proofreading territory, the 1st part (102,112,122) which possesses the average reflectance ratio which displays the layer which is recorded and, offers the particular optical recording carrier (100) which has with the 2nd part (113,123,133) which possesses the average reflectance ratio which displays the layer which is not recorded. In addition, method and the device which form the optimum record power proofreading territory on this kind of entry possible optical recording carrier are offered. These optimum record power proofreading territories are to be piled up part partly, the 1st part of the optimum record power proofreading territory in each opposite of record layer of order with that, forms the single step, the 1st part of the optimum record power proofreading territory of these plural record layers has become ascending form. As for step size of each step which is formed by the opposite of record layer L of order _k and L _{k+1 it} is desirable to make smallest.
