DVD surface, SEM
DVD surface. Coloured scanning electron micrograph (SEM) of the pits that encode information on the surface of a DVD (digital versatile disc). These pits are read by a focused laser as the disc rotates. This is a double-layer DVD, which can hold up to 8.5 gigabytes (GB) of information. This upper layer is semi-transparent and is gold in colour. A second layer (not seen), bonded to the gold layer with a clear adhesive, is coloured silver. After the laser has read the information on the gold layer (from the centre of the disc outwards), the laser refocuses itself on the silver layer and reads from that, from the outer edge inwards. Magnification: x5750 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate surface of a DVD, as captured by a coloured scanning electron microscope (SEM). The image reveals the tiny pits that encode information on the disc's surface. As the DVD rotates, a focused laser reads these pits to retrieve data. This particular double-layer DVD boasts an impressive storage capacity of up to 8.5 gigabytes (GB) of information. The upper layer depicted in this SEM image is semi-transparent and displays a stunning golden hue. However, it's important to note that there is another layer not visible in this photograph. This second layer, bonded with clear adhesive, features a silver coloration. Once the laser completes reading from the gold layer starting at the center and moving outwards, it then refocuses itself onto the silver layer for further data retrieval - this time from outer edge inwards. Magnified at x5750 and measuring 6x7cm in size, this mesmerizing visual offers us a glimpse into the remarkable technology behind DVDs. With its multiple layers and advanced optical medium, DVDs have revolutionized audiovisual storage and playback over traditional film-based media. This extraordinary SEM capture serves as both an artistic marvel and educational tool for understanding how digital versatile discs function as efficient information storage devices.
