Parallel testing of magnetic recording sliders

摘要

A magnetic recording slider test system includes a host to collect test results and initiate concurrent testing of a plurality of magnetic recording sliders. Each of a plurality of first processing units is configured to test at least one element of a respective magnetic recording slider. In one aspect, the plurality of first processing units concurrently tests at least one element of respective magnetic recording sliders. In another aspect, a plurality of first signals is analyzed at respective first processing units, with each of the first signals representing a Direct Current (DC) output from one or more elements of a magnetic recording slider. Results determined from analyzing the first signals are sent to the host. In another aspect, a plurality of second processing units is configured to analyze second signals that each represent an Alternating Current (AC) output from one or more elements of the plurality of magnetic recording sliders.
