An optical analysis disc includes grooves defining corresponding laser-readable tracks and trigger marks that identify respective target regions on the disc. The trigger marks are implemented as a radial interruption of the grooves to thereby produce an increased reflection of a laser beam. There is also provided an optical analysis disc system including a trigger mechanism having a trigger detector adapted to detect interruptions in grooves of an optical analysis disc. A related method for triggering through interrupted grooves of an optical analysis disc includes detecting interruption in the grooves, generating an electrical reflection signal corresponding to the interruptions detected, and elaborating said reflection signal, so that to generate a trigger signal.

Method for triggering through disc grooves and related optical analysis discs and system

An optical disc system includes a photo detector circuit of an optical disc drive and a signal processing system. The photo detector circuit is configured to generate at least one information-carrying signal from an optical disc assembly. The signal processing system is coupled to the photo detector circuit to obtain from the at least one information-carrying signal both operational information used to operate the optical disc system and data indicative of presence and/or characteristics of an investigational feature associated with the optical disc assembly. Methods and discs for imaging a biological or medical investigational feature are also provided.

System and method of detecting investigational features related to a sample

An optical disc drive for reading encoded information, such as on a CD, CD-R, or DVD, is modified to read biological or chemical investigational features from a disc. The modifications can include software changes or the addition of hardware desirably without the need to modify the disc drive electronics.

Disc drive system and methods for use with bio-discs

This invention relates to clinical diagnostic assays, related optical bio-discs, and a disc-reading apparatus. The invention is directed to methods and apparatuses for performing immunohematology assays using an optical bio-disc analysis system. The invention is further directed to an optical bio-disc for performing an immunohematologic assay including a substrate having encoded information associated therewith. The encoded information may be readable by a disc drive assembly to control rotation of the disc. The disc may also include at least one target zone or capture zone associated with the substrate. The target zone is disposed at a predetermined location relative to a center of the substrate. The disc further includes a plurality of capture antibodies immobilized within the target zone, a flow channel, fluidic circuit, or analysis chamber associated with the target zone, and an input site in fluid communication with the analysis chamber.
