Old cassette strips may be re -prevalent with a little change in DNA. While DNA was previously used as an information storage media, the researchers have now easily combined it and the appearance of the cassette tape of the 1980s, leading to something called DNA cassette. It is suggested that you do not miss this from Digino.
Shingo Jiang, at the Southern University of Science and Technology in Guondong, China, along with his colleagues, created this cassette by printing artificial DNA molecules on a plastic strip. “We are able to design the sequence of this tape in such a way that the arrangement of the DNA (A, T, C, G) represents digital information, exactly the same zero and one on the computer,” he says. This means that this cassette can store any digital file including text, image, sound or video.
One of the problems with previous DNA storage techniques was the difficulty of accessing data, so the research team paste a set of barcodes on the bar to help recover information. According to Jiang, the process is like finding a book in the library. We must first find the book shelf, then go to the book. This cassette is also covered with what the researchers described as crystal armor made of zeolites’ imidazulats, which will prevent the decomposition of DNA bonds.
This means that DNA cassette can store data for centuries without damaging. While a regular cassette tape could store about 2 songs on each side, 2 meters from the DND cassette tape would be able to accommodate more than 2 billion pieces of music with a volume of 2 MB per song. The total capacity of data storage is 2 pinky, equivalent to 4,000 terabytes of hard drive.
However, a team member from the South University of Science and Technology says that if you put one of the new strips in a Walkman, it will not produce any significant sound because DNA cassette does not use its former model magnetic signals. “Our bar carries DND molecules, in other words, it is like trying to play a photo in a audio recorder, while their format is not compatible,” he added.
