History of Magnetic Tape & Magnetic Disks
Magnetic tape and magnetic disk media are used for data storage.They have developed and changed over the years, getting smaller while holding more information.
As a rule, size of media has moved from being enormous and very inefficient, to tiny and ultra-efficient. We have seen magnetic tape with a 2-inch width being replaced by micro-miniature disks holding hundreds of times the capacity and with much more redundancy.
Magnetic tape and disks have been used to store all manner of material, from raw data to music and video. They were found to be…
Hard drive storage is quite different from magnetic tape, though both of them are usually used for backup solutions. Both technologies operate on the same basic principles, which have been in use for over 60 years. The benefits and pitfalls of each make them best suited to different situations, however.
Basics of Magnetic Storage
On any magnetic storage medium, information is encoded into binary, then recorded by setting the polarity of many tiny regions on the media. This pattern of positives and negatives is a relatively resilient form of non-volatile memory and forms the basis for the majority of…
Your laptop computer’s hard drive is where it stores all of your data. Everything from your pictures from last year’s vacation and favorite MP3s to last year’s tax returns are all stored on some sort of hard drive. If you have a laptop computer, there are a few different hard drive options for you to choose from, each offering its own unique benefits.
1.8" Hard Drives
The 1.8" hard drives are designed much like 2.5" drives, only smaller. The compact drives are typically used in smaller notebook computers or netbooks. Some companies also use the drives for storage in MP3…
What is Solid-State Hard Drive?
A solid-state hard drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive interface, thus easily replacing it in most applications. An SSD using SRAM or DRAM (instead of flash memory) is often called a RAM-drive, not to be confused with a RAM disk.
The original usage of the term solid-state (from solid-state physics) refers to the use of semiconductor devices rather than electron tubes, but in this context, has been adopted to distinguish solid-state electronics from electromechanical devices as well. With no…
