拾音器循迹能力这项指标在六十年代才提出来,很快就引起各国重视,并成为新型拾音器设计的重要依据。在 IEC 有关文件中对循迹能力的阐述和测试方法的规定,也随着人们认识程度提高而逐渐深化,1982年颁布的 IEC98~#文件讨论稿则对此提出更为明确的建议。本文就国外有关论著作一简介,供拾音器设计方案探讨及评定性能时作参考。

Pickup Tracing Capability This indicator was put forward in the sixties and soon attracted the attention of all countries and became an important basis for the design of the new pickup. The interpretation of the ability of tracking and the test methods in the relevant documents of IEC are also gradually deepened with the improvement of people’s understanding. The IEC98 ~ # Discussion Paper promulgated in 1982 made a clearer proposal. In this paper, a brief introduction of the relevant foreign works for the design of the pickup to explore and assess the performance for reference.
