In an information recording medium comprising at least a substrate, a recording layer, and a resin layer, the substrate is formed with at least a pit corresponding to a read only area 31 and a groove corresponding to a recordingreproducing area 32 without overlapping with each other. Known failure mechanisms related to layout geometries are used to derive yield functions based upon distance values between layout features, such as, edge features. A bump is disposed on the bonding pad and projects from the bonding pad by a predetermined height. The height adjustment member has a plurality of radially directed, angularly separated arms of different lengths, wherein an end portion of such an arm is adapted to engage with an adapted engaging portion of the slide.
