WebModified frequency modulation (MFM) is a run-length limited (RLL) line code used to encode data on most floppy disks and some hard disk drives.It was first introduced on hard disks … WebWhen you apply power to a drive, MCU chip reads content of the flash chip into memory and starts the code. Without such code drive wouldn't even spin up. Sometimes there is no flash chip on PCB that means content of the flash is located inside MCU. Shock sensor can detect excessive shock applied to a drive and send signal to VCM controller.
