What is a Hard Disk Platter?

This is a round magnetic disk coated in aluminum and ceramic located within the computer that facilitates permanent storage of data. The hard drive houses a set of hard drives which rotate on the same spindle at high speeds of up to 7200 revolutions per minute, however this speed may vary depending on the nature of the hard drive. During the rotations, the read write head — just as the name suggests – entrees the information from either side of the drive sectors, tracks or the cylinders availing it to the computer once the computer is turned on.


Each platters magnetic surface is partitioned into micron thickness which in turn act as a representative of a binary unit of information. The conventional size of a platter extends between 200 – 250 nanometres In width and towards the Stella region and 25 – 30 nanometres in towards the underside creating an equivalence of 100 billion bits within a square inch. Within The cobalt coated magnetic hard-disk exists a handful magnetic grains which in turn gets magnetized during the rotating. This ensures that the entire region gets magnetized.

Magnetic grains are appropriate within the hard-disk prior to to the continuous magnetic materials in that they create a favorable lesser magnetic space within the region preventing the formation of the Neel spikes: the spikes cancel their own magnetic field such that at the boundaries magnetization would only have to occur along the transition width.

The reduction in granular sizes of modern day ensures that only a single magnetic domain is created. Since magnetic domain neither grow nor shrivel, it will be therefore plausible to argue that no spikes will be formed and that the transition width will then follow the length of the granules sizes-a welcome move why the hard-disk platters would need the smaller grains.

Composition of the Hard Disk Platter

Just like noted earlier platters are encompassed of aluminum, ceramic and glass as the major ingredients. These three are brought together by applying a thin coat to each by a vacuum deposition in a process known as sputtering. The coating is a compilation of several metallic alloys that are designed to control the grain sizes orientation on the existent magnetic media. A protective carbon layer is then spread sparingly through the sputtering process. A very thin polymeric lubricant is then greased on the sputtered structure through immersion in a solvent after which the disk is screened for impurities or defects using a special sensor. The hard-drive heads within the hard-disk make radial movements all over the surface of the rotating platters to access data. For the process to be termed successful, a smooth, long lasting and perfect hard disk platter should be given off as the product.

Final Say

The quest for special platters has been on the rise since 2000 which necessitated the transition from the aluminum to glass platters due to their comparative advantages. The inception of the special technology back in 2005 led to the replacement of magnetic technology by perpendicular recording. With even a stronger quest for stability and density, further revolutions with disk-platters are anticipated.


The Much Awaited Mini Tool Power Data Recovery Version 7.0 Is Out

The much awaited Mini Tool Power Data Recovery Version 7.0 is eventually out. This wonderful tool comes with a new interface and lots of other features to give the user a new experience in data recovery.

The new version features a new scanner which has the excellent ability to scan files quickly thus saving on time. It is the best option for those who have been experiencing slow performance when scanning their data using previous versions of mini tool power data recovery. The software has been proven to increase the efficiency of scanning a large database by 50%. This makes it awesome because users will spend less time to recover many files. In addition, its new interface is easy to use. The user will not require any prior knowledge or technical experience. This makes it an excellent choice.

What really makes mini tool power data recovery version 7.0 great is the fact that it is compatible with almost all window versions. This ranges from Windows 95 to Windows 10. This will enable many users to enjoy its extraordinary functionality.

There are certain requirements that all users of this tool should be aware before beginning to use it. One such requirement is that the system should have pentium-class processor IDE or SCSI hard drive with a RAM of 64MB. In addition, it should have a minimum free space of 100MB.

Furthermore, for successful recovery of lost data, users are advised to have a second hard disk drive. This will also make the process easy and convinient.

According to the developer, this amazing tool can perform various functions. They include damaged partition recovery, digital media recovery; undelete recovery and CD/DVD recovery.

Unlike other tools that recover limited amount of data, mini power data recovery version 7.0 will enable users to recover unlimited data except when you choose the free licence compaction which has a maximum data recovery of 1GB.

Besides, it comes with three types of licence which vary in price and differ in terms of services provided. For instance free licence which allows users to perform different types of recovery except loading previous recovery result. Personal licence offers more services and enables users to recover unlimited amount of data.

The third licence compaction is called personal licence & bootable media builder. It is the most expensive but has the best services. It allows users to perform all the basic data recovery functions, enables them to recover unlimited amount of data, load previous recovery result and even recover data after system has crashed , the OS has failed to boot or the computer is experiencing booting problems.

It is evident that the new version comes with excellent features and amazing functionality that will make it very helpful to users.

How to Back-up your Data

Learning ways of avoiding loss of data is something that many never put into consideration. It may take a few Hard drive failures until you recognize that you want to understand ways of avoiding data loss in future. Many of us have lost many important files, pictures, and documents. The following are tips on How to Back-up your Data.

Store them on your other PC

If you have more than one PC, you can store important on each other by zipping them of course, to minimize disk usage. One downside to this is that consumes up a lot of disk space in your PC and may slow down.

Copy them in DVDs

One of the easiest ways to back up your files is to store them in DVDs or CDs. DVDs have a higher storage capacity than CDs. Thus you may want to choose the first option to make less bulky if you want to bring along your backup of data if you go on traveling.

Attach them in your email

This is one of the freeways to store your data and files online is to send them to your second email as an attachment. Emails these days support large attachments and have larger storage capacity, so you can also take advantage of that as your online storage. Another good thing about the backup of data is you can access your files everywhere for as long as you have internet access.

Use online storage sites

Although most of these sites collect a fee or storage, some may also offer limited but free storage. For as long as your files do not exceed the limit of the free cloud storage service, you can avail of this online storage without any costs. However, if you want to make your files secure in one place and you want to be accessible online, availing of online storage sites can also be a good option.

Use your external HDD

Portable external drives are also great storage for your files and data. They are portable so you can also enjoy the convenience of bringing around and they have much bigger capacity than DVDs so that you wouldn’t be bringing a lot of them too.
