ABSTRACT:
An integrated calibration apparatus operates in multiple calibration modes of a multi-mode information storage system such as an optical disk drive to calibrate the drive in the multiple write modes. An event processing and measurement circuit is configurable in multiple configurations that each correspond to a different calibration measurement. Each configuration concurrently measures one or more parameters of readback data written to an optical disk by the optical disk drive operating in a particular write mode. A qualification circuit selects valid measurements for two different parameters or for two different qualification of the same parameter. A summation circuit sums valid measurements of each parameter measured and counts the number of measurements summed for each parameter. The calibration apparatus calculates average values for the measured parameters from the sums and counts, and then calibrates the multi-mode optical disk drive for its current write mode based on the average values.
