    A recording or reproduction device with a three-point scanning arrangement compatible for use with recording media having different track spacings. The invention makes it possible, without changing the setting of the three-point scanning system, to use recording media having different track spacings. According to the invention, the three-point scanning system is set in such a way that the scanning center points have a lateral spacing from one another which is within a range of a first product, The midpoints of the scans are laterally spaced with a separation chosen as about 7/4 times the smaller track spacing, and about 3/4 of the greater track spacing. The tracks may be either spiral or parallel.
