Optical information storage medium reproduction apparatus and control method of the same

A reproduction method for reproducing a rewritable and readable optical information storage medium in such a manner that an information recording layer, in the rewritable and readable optical information storage medium, that is closest to a reproduction-laser-incident surface of the rewritable and readable optical information storage medium is read by irradiating thereto a reproduction laser having power lower than that of a reproduction laser for reading an information recording layer, in the rewritable and readable optical information storage medium, that is farthest from the reproduction-laser-incident surface, said reproduction method comprising:

• reading setting information of reproduction laser power for each information recording layer of the rewritable and readable optical information storage medium, the setting information being stored in the rewritable and readable optical information storage medium;
• and
• setting, based on the setting information thus read, reproduction laser power for the information recording layer that is closest to the reproduction-laser-incident surface to be not less than 1.0 mW but less than 1.1 mW.
