摘要： An optical information recording apparatus and an optical information recording method are provided to improve recording quality by setting write strategy in over-writing although an over-write operation is performed in a rewrite-type optical recording medium. A control unit(8) judges whether an area for recording information is a previously written area of an optical recording medium. When the area for recording the information is the previously written area of the optical recording medium, a write strategy setup unit(6) over-writes the information and sets write strategy. The write strategy setup unit(6) over-writes the information in a test recording area of the optical recording medium, and sets the write strategy.

摘要： A dual stack optical data storage medium (30) for recording and reading by means of a focused radiation beam (29) is described. The beam enters the medium (30) through a first radiation beam entrance face (21). The medium has at least a first substrate (la) with on at least one side of the first substrate (la) a first layer stack (2), comprising a first information layer (3), a second layer stack (5), comprising a second information layer. The second layer stack (5) is present at a position more remote from the first radiation beam entrance face (21) than the first layer stack (2). A first transparent spacer layer (4) is present between the first layer stack (2) and the second layer stack (5). The first information layer (3) is a read only type layer or an organic write once type layer, and the second layer stack (5) consists of maximally three adjacent layers of an inorganic metallic material. In this way an optical data storage medium (30) is achieved which is compatible with a dual stack ROM version of said medium and which has a simple second layer stack (5).
