Motion Controller Helps Test for Hard Disk Defects

Hard disks were originally intended for computers in ultra-clean, ultra-safe data offices; by the 21st century, hard disks had moved beyond the office, finding their way into digital cameras, video recorders, PDAs, and cell phones. With the ubiquity of hard disks comes the risk that any number of electronic devices can fail if their hard disk crashes. To detect hard disk defects while still in the assembly stages, THôT Technologies (Campbell, CA) developed the Model 42000, a laser-based test and measurement system for hard drives’ disks, using the DMC 1832 3-axis controller from Galil Motion Control (Rocklin, CA) to help monitor and regulate various systems of the Model 42000 as it conducts testing.
