Theplatteronwhichavinylrecordisplacedfeaturesatwo‐layerstructurewithdeadeningrubberontheentirebacksurfaceto
eliminateunwantedresonanceinthealuminium die‐castplatter.Theplatteroffershighrigidityandoutstandingvibration‐
dampingcharacteristicstopreventharmfulvibrationfrombeingtransmittedtotherecordanddeliversclearsound.
Toincreasetheinertialmassandminimise vibration,theshapeofthealuminium die‐castsectionwasoptimised through
simulation.Forextrarigidity,reinforcingribswereaddedtothebackside.Theincreasedareaofcontactwiththedeadening
rubbercontributestotheoutstandingvibration‐dampingcharacteristicthatismorethantwotimeshigherthanthatoftheSL‐
1200MK5.
