As compared to magnetic memory, optical memory is a relatively new secondary storage medium. FS.COM, as a leading optics supplier, provides all kinds of optical fiber cables with high quality and low price for your option. A disadvantage to optical storage would be its limited ability to go in and modify what is stored on a cd, dvd, or blu ray disc. Advantages of CDs Disadvantages of CDs; Small and portable: Fairly fragile, easy to snap or scratch: Very cheap to produce: Smaller storage capacity than a hard drive or DVD: Most computers can read CDs. Introduction: The OCR not only detects the presence of characters but also differentiates them by their shape. Fiber optic cable has both advantages and disadvantages. It must be stored in a dust-free environment in order to protect them from crashing down. Advantages of Optical Disks. Optical materials have greater accessibility and storage density than magnetic materials. So the optical computer technology has the potential to change the shape and layout of computers fundamentally. 1. • Describe the advantages and disadvantages of magnetic storage, optical storage, and solid state storage using criteria such as versatility, durability, capacity, access time, and transfer rate. Advantages of Cloud Storage. Computers use many different types of mediums for the storage of data. # ... Optical Storage Media . If there is no CD drive, a DVD drive can usually read them: Slower to access than the hard disk. Cloud computing storage services advantages, disadvantages, use & features. Physical:An optical disc is much sturdier than tape or a floppy disk. Still the data rate is very high and there is no crosstalk. Optical storage devices offer advantages over other high-capacity storage such as microfilm and tape in that they have faster access times.
A single sided DVD can store about 4.7Gb of data. Cost Purchasing physical storage can be expensive. • Magnetic disks are sensitive to be touched where as optical disks are not. The development of greater optical storage capacity, while slower than that of HDD or solid-state drives, hasn't stopped.
