Read Head Resolution and Repeatability

Read head resolution and repeatability are two important concepts that directly affect read head performance. This article introduces the concepts for read heads and discusses their practical importance.

Resolution refers to the smallest display increment a read head can show. Higher resolution yields finer measurement precision—for example, 0.01 versus 0.1 units. Choosing the correct resolution is crucial for measurement accuracy.

Repeatability measures the consistency of repeated measurements under the same conditions. High repeatability means reliable measurement results. Even with high resolution, low repeatability undermines trust in measurements.

In practice, resolution and repeatability complement each other. Only when both are sufficient can the read head provide accurate and reliable results, so both should be considered when selecting a read head.
