WHAT IS OPTICAL STORAGE •Optical storage is data that is stored on optical readable medium. Magnetic tape. Tape drive is used to read and write data on tape. Hard disk. The Magnetic disk and Optical disk are the storage devices provides a way to store data for a long duration. Looks like you’ve clipped this slide to already. Teaching tip This process is difficult for students to see. Previous - Solid State Storage Media . Presentation of the big external memory Luis Fernando. Magnetic tape is the oldest storage device. This … Teaching tip There are several formats of DVD recordable. Spend time researching the different standards. Discuss the perils of typing papers on a typewriter. Teaching tip Students often have a hard time grasping the speed of a hard drive. Secondary Storage Devices: Magnetic Disks Optical Disks Floppy Disks Magnetic Tapes - Hard disks (high capacity, low cost, fast) Floppy disks (low capacity, ... o kilobyte (KB): 1024 or 210 bytes. b) It is affected by magnetic field. Primary Storage. Storing data : Disk Organization and I/O Computer Hardware & Trouble shooting. Then contrast with the simplicity of saving to disk. Teaching tip The formula for the disk capacity is listed on page 232 of the text. See our User Agreement and Privacy Policy. Storage Devices and Media : The course syllabus states that you should be able to: (a) Describe the following common backing storage media and their associated devices: Fixed hard discs, Portable hard discs, Magnetic tapes, Optical backing storage media such as CDs and DVDs, CD ROM/DVD ROM, CD R/DVD R, CD RW/DVD RW, DVD RAM, Blu-ray, Solid state backing storage, Memory sticks/Pen drives, … Hard disk & Optical disk (college group project), No public clipboards found for this slide. a) Stores data optically & used laser to read/write. A USB drive? Teaching tip A good warm-up to storage devices is to discuss the time before we could save items on disk. Optical Storage 1. • describe the principles of operation of a range of types of storage device and media including magnetic, optical and solid state • describe how these principles are applied to currently available storage solutions, such as SSDs, HDDs, USB flash memory, DVDs, CDs and Blu-ray discs • calculate the storage requirement of a file. NOTE: ... Next - Optical Storage Devices. This type of optical storage device is somewhat unaffected by the presence of magnetic fields and thus, can be considered as the optical equivalent of magnetic hard disks in computers. To illustrate, compare the modern audio CD to the antiquated 8-track. Portable hard disk. If you continue browsing the site, you agree to the use of cookies on this website. Secondary Storage Devices Two major types of secondary storage devices: 1. Section 6: The Effects of Using ICT. Teaching tip Figure 6A.2 and 6A.3 on page 227 provide illustrations of devices and the read/write process. See our Privacy Policy and User Agreement for details. storage devices include magnetic hard drives, optical drives (CD or DVD), flash/pen drives, etc. Definition of Magnetic Storage. After the waste issue is brought up, then discuss the problem from the hardware issue. Hardware components that read/write to storage media are called storage devices. Optical storage provides greater memory capacity than magnetic storage because laser beams can be controlled and focused much more precisely than can tiny magnetic heads, thereby enabling the condensation of data into a much smaller space. Section 4: Computer Networks . magnetic and optic based storage devices Sarab Singh. Section 7: The Ways in which ICT is used. Types of storage magnetic, optical, magneto-optical, solid state Storage characteristics Magnetic storage: | PowerPoint PPT presentation | free to view SECONDARY STORAGE DEVICES - SECONDARY STORAGE DEVICES Y.Colette LeMard FLASH MEMORY You may recall that EEPROM can be erased by using high voltages. No public clipboards found for this slide. Clipping is a handy way to collect important slides you want to go back to later. When an optical drive shines light into a pit, the light cannot be reflected back. Data is stored on magnetic tape in the form of magnetic spots. In magnetic storage devices, data is stored on a magnetized medium. Two main categories of storage technology used today are magnetic storage and optical storage. Direct Access Storage Devices (DASDs) Magnetic Discs Hard disks (high capacity, low cost, fast) Floppy disks (low capacity, lower cost, slow) Optical Disks CD-ROM = (Compact disc, read-only memory 2.
