Data storage mediums and the Development of Technology

Data storage mediums and devices have been absolutely crucial to the development of most every modern technology there is. From the hand held digital audio player in your pocket, to the personal laptop computer in your bag, to the Blu Ray player you have at home, all of these devices rely on a variant of the same technology which allows them to write and read, and subsequently, process various data types; the .mp3s on your audio player, the text documents on your laptop, and the video and audio off of a Blu Ray disc on your Blu Ray player. Let’s take a look at the three most predominant types of mediums that exist today.
The laptop or desktop that you are likely currently using to read these words use what’s known as a hard disk drive. It’s core components consist of one, two, or more, rapidly spinning magnetic disks that are known as platters. An “arm”, as it is dubbed, extends over the platter when it is in operation, conveying data that was previously written to the disk to the device in which it is being used, or overwriting old data with new data that is being assigned to be written by that earlier mentioned device. Originally developed by IBM in 1956, it has now become the most popular storage medium for use in computers, but with new advancements in the development and manufacturing of Flash Memory, the mechanical, failure-prone hard drive medium is a dying breed that will eventually be entirely replaced by it’s solid state brethren. Speaking of computers, if you are having trouble obtaining one due to debt consolidation issues, you may need some Credit Counseling. In this area, the Community CCC can be of tremendous help to you in finding superb Credit Counseling help, I highly recommend them.
Your optical media mediums; Blu Ray, HD DVDs, CDs, are a bit different from the previous two. Like hard drives, the medium requires is and requires a spinning disc. However, the aparatus used to read and write data is quite different, and the medium itself, has differences as well. You’ve no doubt layed eyes on a CD or DVD before; it consists of a polycarbonic plastic based disc with a reflective material layed in on one side of platter.
