APPARATUS FOR THE INSPECTION OF COMBINED READ/WRITE HEADS OF DATA CARRIER DISKS IN EDP INSTALLATIONS |
摘要 |
An inspection apparatus for the read/write heads of data carrier disks in electronic data processing equipment is provided with a mirror holder with approximately two parallel sides between which extends a deviating mirror and a viewing mirror and at least one lamp is arranged on one side; a positive lens is positioned approximately at right angles to the optical path from the viewing mirror to the deviating mirror, the focal length of which is greater than the optical path from an object to be observed in the vicinity of the viewing mirror to the principal plane of the positive lens; a prism mirror may be placed in the plane of symmetry which extends through the mid point of the second mirror to facilitate viewing. |
