John Lynott and William Goddard, together with Louis Stevens and a team of engineers,
invented a unique magnetic disk storage device at the IBM Lab in San Jose in the 1950s.
The magnetic disk drive replaced data stored on punch cards and magnetic tape with
almost instant, direct access storage and retrieval.
The magnetic disk drive consisted of a stack of closely spaced,
magnetically-coated disks mounted on a rotating shaft, with read-write heads
which did not physically touch the storage surface.
Lynott and Goddard key contribution was the air-bearing head,
which “floated” very close to the rotating disks without actually touching,
greatly increased the speed of access.
The invention validated IBM lab director Reynold Johnson’s vision that
disk storage could be made practical, provided quick, efficient access to
large amounts of data, ushering in a new era of interactive computer applications,
such as airline reservation systems and personal computing. Today's magnetic disks
are dramatically smaller and faster than the original, but many key features of
Lynott and Goddard’s team’s design are still found in modern disk drives.
By 2003, the computer industry produced 260 million disk drives each year.
Born in Johnson City, New York, Lynott attended Syracuse University.
He earned 25 patents for his work in mass-data storage during his 27-year career at IBM.
