Appendix I: Magnetic Heads Mechanical Design Guidelines; Track Locations - IDTECH SecureHead User Manual

13. APPENDIX I: MAGNETIC HEADS MECHANICAL DESIGN
GUIDELINES
This section defines the design specifications ID TECH customers require to install magnetic readers and heads to the
correct dimensions and other specific requirements that ensure maximum life and reading reliability. ID TECH has
spent years testing magnetic heads with our electronics to determine the best dimensions and characteristics. These
factors, combined with the specified reference surface, provide for ID TECH's industry-leading reading reliability. It is
extremely important to follow these instructions to achieve the best performance for ID TECH magnetic reading
components that are designed into your product(s).

Track Locations

ISO 7810 and ISO 7811 standards define the specification for all "standard" magnetic stripe cards. The location of
each magnetic head's track's centerline is shown below in Figure 1
that have mounting holes located on the centerline of Track 2; refer to Figure 2 for the 3-track standard magnetic head
and (wing) spring mount. The pivot pins must be precisely located to the dimensions shown below in Figure 1 for the
Track 2 centerline, ensuring the read head will be to the proper dimensions for all tracks.
Note: Magnetic heads can contain one, two, or three tracks, but a three-track head is the most common.
