Magneto-Optical Disk Drive Research
Agilent Technologies pulse generators contribute to CD-ROM technology research.
To write to and erase a bit pattern from a magneto-optical disk, a laser generates pulses at different write and erase voltages and pulse widths. In research, it is necessary to experiment with writing and erasing over the same spot on the disk every disk revolution. Writing, places a “1” on the disk, which orients the magnetic fields at that spot in a specific direction. Erasing on the other hand, places a “0” on the disk and orients the magnetic field in the opposite direction.
