Abstract: A method for displaying microarray information by which unknown but useful information is extracted from a mass amount of sample information obtained with microarrays. Luminescent intensity information of sample spots obtained with the microarrays is standardized for each microarray and displayed as a graph as a difference from the standardized luminescent intensity of a sample spot of interest. Accordingly, information can be compared without being influenced by a difference of experiment status between the microarrays or a difference of physical properties between the samples. A three-dimensional graph is displayed by sorting the set of samples and the set of microarrays to which the sample spots belong, under predetermined conditions, and assigning the set of sorted samples and the set of sorted microarrays to X-axis and Y-axis, and the accumulated luminescence intensity to Z-axis.

Abstract: An optical disk that enables high-speed reproduction of address signals. A wobble address system for optical disk supports various types of synchronization, such as phase synchronization, bit synchronization, word synchronization, etc., to be established easily with high detection reliability with the use of an self-orthogonal code. Thus, the invention provides a method for easily synchronizing an address signal, i.e., high-speed reproduction of the address signal. Further, by virtue of an efficient modulation system of the address signal and redundancy thereof, it becomes possible to detect address information with high reliability. This capability is particularly effective in optical recording/reproduction with a blue light source whose signal light quantity and reproduction quality are prone to reduce.
