Scientists create world's smallest record

Scientists in Denmark have created the world’s smallest “vinyl” record, which is so tiny that it can barely be seen by the naked human eye, EDM reports. Measuring just 15x15 micrometres, with grooves of a depth of just 65 nanometres – the tiny record contains music - it plays 25 seconds of ‘Rockin’ Around The Christmas Tree’, in stereo. Professor Peter Nøggild explained that the technology could be critical in future scientific research: “While we make these kinds of grooves here with nanometre precision, we can transfer these to a number of other materials, where that will fundamentally allow us to manipulate material properties on a nanoscale.”
