Laser writing optical data onto adhesive tape
Optical storage tape. Researcher observing a semiconductor laser (blue) writing data onto different layers of a roll of plastic adhesive tape. The laser is reflected by a rotating mirror (centre left) and focused onto specific points on the tape, altering the refractive index (RI) of the tape. By altering the RI at various points of the tape, information such as images, sound and computer data can be stored without the tape being unwound. This roll of tape can store up to 10 gigabytes of data. The device is being developed in Heidelberg, Germany, by the European Media laboratory (EML) in cooperation with the Mannheim University

EDITORS COMMENTS
In this photo print, we witness the cutting-edge technology of laser writing optical data onto adhesive tape. A researcher in Heidelberg, Germany, closely observes a semiconductor laser emitting a brilliant blue light as it meticulously writes data onto different layers of a roll of plastic adhesive tape. The mesmerizing process involves the laser being reflected by a rotating mirror positioned at the center-left of the image and then focused onto specific points on the tape. What makes this innovation truly remarkable is that it allows for information storage without unwinding the tape. By altering the refractive index (RI) at various points on the tape, an array of valuable content can be stored – from images and sound to vast amounts of computer data. Astonishingly, this single roll has an impressive capacity to store up to 10 gigabytes worth of information. The European Media Laboratory (EML), in collaboration with Mannheim University, spearheads these groundbreaking advancements in optical storage media. This research project showcases their commitment to pushing boundaries and revolutionizing how we store and access digital content. As we delve into an era where technology plays an increasingly vital role in our lives, developments like these remind us that progress knows no bounds. With each passing day, scientists continue to unlock new possibilities for storing vast amounts of information efficiently and securely – paving the way for future innovations that will shape our world in unimaginable ways.
