  • System and method for servowriting a magnetic disk drive
    Patent number: 5339204
    Abstract: A magnetic disk drive is provided with a system and method for writing a servo pattern after the head disk assembly (HDA) is sealed. A clock track is written inside the sealed HDA using a Monte Carlo technique. The clock track is read by a magneto-optical head through a window in the HDA housing, and the time transitions therefrom are used to control the product heads. The entire servo pattern for the disk drive is thus written with the HDA unit completely sealed.
