maybe you remember the technology used for the Nakamichi TX 1000 – self centering the record on the platter by a mechanism below of the platter moving the platter in an “in Center position” after having measured the deviation. Or the latest but expensive invention by DS Audio ES 001 – eccentricity detector centering the hole of a record by cutting out the exact hole in the middle of the record, moving the record in the center position for letting the record turn in an absolute balanced spinning turn. There is no moving of the record anymore. So the stylus tracks the record’s groove without moving too much sidewards inside of the groove depending on the record’s off center cut hole.

I sold my Nakamichi TX 1000 to the US, it came from Hawaii and was modified at me – look at “good old times” on this blog.

I need to check the DS system, also to assess the process of enlarging the hole. Will tell you what is the result. I may try it on this SDP Micro Seiki table:

the advantage of the additional SDP platter is that you have no fixed spindle rotating directly on the turntable’s bearing.
