Data is written by two million laser beamlets that punch QR code-like nano-scale patterns into the surface of the media. The laser pulse is sharpened by a digital micromirror device, and shaped by microscope optics onto the surface of the data carrier. This process imprints holes – or no holes – onto the surface layer, which represents binary information.

It’s futuristic punchcards. We’ve come full circle.

A punchcard is two dimensional. Actually you can have multiple dimensions on a punch card, the positions of the card can store different data and you can determine what that is by the position of holes on another part of the card.

Whereas a paper tape, or a magnetic tape is serial and has only one dimension (you can divide the tape into different bands though).
