Frank Schröder has designed a linear tracking pivotal tonearm. He claims it has zero tracking error, zero skating force, and zero friction bearings. It appeared to work as advertised and it sounded great. The pivot-to-spindle distance decreases as the arm moves across the record in order to maintain zero tracking error. The headshell has no offset so it presumably should have no skating force. I thought it was quite intriguing and very innovative, so I'm hoping we will be able to learn more about how it works in the future.
Best regards,
