Patent ID: 6879454

Claim:
A method for implementing a write-once read-many functionality for storage of data on a rotating disk drive data storage device containing at least one rotatably mounted disk for recording data on at least one surface of said at least one rotatably mounted disk and a movable actuator supporting at least one transducer head, said actuator positioning said at least one transducer head to access data on said at least one surface of said at least one rotatably mounted disk, comprising the steps of: a. determining that data has been written to a portion of said rotating disk drive data storage device; and b. responsive to said determination, blowing one or more fuzes electrically coupling a write signal to said transducer head, wherein said write signal is required at said transducer head to enable said transducer head to write data to said portion, and wherein blowing said one or more fuzes prevents said write signal from being received at said transducer head, thereby preventing said rotating magnetic disk drive data storage device from overwriting said data written to said portion.
