TLDR The video explores the history and evolution of compact discs (CDs), from their inception in the 1970s to their peak in the early 2000s. Despite being overtaken by digital and streaming technologies, a breakthrough in optical storage technology could revive CDs. Researchers have developed a 3D optical disc with a staggering 1.6 petabytes of storage capacity, equivalent to 200,000 DVDs. This new technology uses advanced materials and nanoscale techniques, making it suitable for data centers and long-term archival storage. However, challenges such as market adoption, writing speed, and cost remain significant hurdles.
Takeaways
» Click to show Spoiler - click again to hide... «
😀 CDs were once a popular medium for music and data storage, offering a unique experience of flipping through discs and enjoying high-quality audio.
🚀 The concept of CDs dates back to the late 1970s, with Philips developing the technology for audio discs using laser reading, which was a futuristic idea at the time.
🔄 Philips and Sony collaborated to combine their expertise in laser technology and digital audio circuitry, leading to the creation of the CD and the establishment of standards in 'The Red Book'.
💿 The first commercial CD player was introduced by Philips in 1982, and CDs gained popularity due to their superior audio quality compared to vinyl records and tapes.
📈 CD sales peaked in the year 2000 but declined significantly due to the rise of digital file sharing, MP3 players, and streaming services.
🔄 Researchers have developed a 3D optical disc with an unprecedented storage capacity of 1.6 petabytes, which is a significant leap from traditional CDs.
📚 The new optical disc uses advanced materials and nanoscale data spots to achieve high-density data storage, overcoming the limitations of visible light wavelengths.
💡 The writing process for the new disc involves a complex laser technique, using green and red lasers for spot formation and writing control.
🔍 The reading process employs a blue and orange laser duo to accurately reveal the stored data on the disc's layers.
🏢 These ultra-high-capacity discs could be beneficial for data centers, offering a more compact and durable solution for long-term data storage compared to current technologies.
🚧 Despite the promising potential, there are significant challenges, including market adoption, slow writing speeds, high energy consumption, and the high cost of the required equipment.
WW3 era offline entertainment plan B, when online thing collapsed, any network is only for military folks. It's like those movie "leave the world behind" kid ending when she finally can watch Friends again.

Cloud storage is the way to go. Network and monthly payments is affordable now.
People don't want the trouble of keeping the CD and reader.
Maybe the tech isn't for consumer, but for large scale data centers. Instead of an array of drives to get 1 petabyte, you just need a single disc. Thats like a microwave oven reduced to a size of a waffle.
