Abstract
Abstract The performance of a computer may be evaluated by measuring the movement of the read-write head of the disc information storage of a computer, and the speed of revolution of the disc. A signal is relayed to an external recorder to disclose movement of the head and the disc speed. A number of other performance criteria may be determined from these. There is no electrical connection between the sensing system and the internal electrical system of the computer or storage system.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
66 words
In a computer information storage system comprising an information storage disc having a number of information storage cylinders thereon, means for transferring information to and from said cylinders, means for moving said transfer means among said cylinders, the improvement comprising means attached to said information storage system for sensing the movement of said transfer means, and means responsive to said sensing means for recording said movement.
Claim 2
Dependent Claim
66 words
In a computer information storage system comprising an information storage disc having a number of information storage cylinders thereon, means for transferring information to and from said cylinders, means for moving said transfer means among said cylinders, the improvement comprising means attached to said information storage system for sensing the movement of said transfer means, and means responsive to said sensing means for recording said movement.
