KYREAD MAGNETIC TAPE/DISK DEVELOPER

Kyread is a stable suspension of small magnetic particles useful for visually "developing" magnetic images on tapes and disks. On contacting the written tape or disk, the particles are attracted to the magnetized areas until these are fully delineated. Kyread developer is used to check recorder head alignment; track placement, dropouts, and interblock spacing; skew and noise; to cue for splicing; and to synchronize video or audio tape (when recorded at high or saturation levels). The particles are of two types: Regular; Spherical, silvery iron particles of 1-3 micron diameter and XF ("extra fine"): Spheroidal, black iron exide particles of .05 micron diameter.

Kyread SDF-130A: 1) has near-zero effect on the ozone layer and the environment. 2) Evaporates quickly. 3) Is non-flammable and non-toxic. 4) Has negligible effect on polymethacrylates and most other plastics used in cassette bodies and reels and magnetic costings on tapes, disks and cards. Surface attack and clouding have been noted with some polystyrene blends. Test Kyread SDF-130A for effect on materials and components before using.

Directions for use:
1. After shaking, apply to inclined magnetic card, tape or diskette with a cellulosic paper or tissue as backing to absorb excess Kyread. This immediate removal of excess Kyread yields a distinct and clean visual trace.
2. Remove Kyread trace with cleaning cloth or Scotch removable tape #811 or "Post It" adhesive backing (3M Co.) or equivalent.
