CONTROL METHOD FOR A RECORDING DEVICE

摘要

A preferred embodiment of a method for developing a single set of time intervals for controlling a memory device effectively utilizes a histograph having two parallel time lines with the same scale. One time line has a series of minimum time periods, each corresponding to when a respective event might occur. The other time line has a series of maximum time periods during which the respective events might occur. Time segments are defined between corresponding minimum and maximum time periods and sample rates and ratios are assigned to each time segment. At each start and end time of a period, the possible sample rates needed at that time are compared and the fastest sample rate is selected. The ratios are similarly analyzed, and the minimum ratio is selected. Consecutively occurring sample rates having the sample value are grouped into respective time intervals. The resulting time intervals, sample rates and ratios are entered into an electronic memory device which thereafter operates to obtain the desired information at the selected ratios and sample rates during the respective time intervals.
