Perpendicular Storage Technology

Perpendicular recording is a recently implemented technology for data recording, which has come to counter the ever increasing need for more storage space.Current hard disk technology with longitudinal recording has an estimated limit of 100 to 200 gigabit per square inch due to superparamagnetic effect. With longitudinal recording reaching its limit of maximum capacity, perpendicular recording would enable us to store 10 times more data.


Above image demonstrates both the recording techniques, in longitudinal we store the bits of data in west-east direction or horizontally but this impose the limitation of minimum gap between two consecutive bits which we need to maintain in order for data to be in a readable format this is known as superparamagnetic effect.

Perpendicular arrangement or vertical arrangement of bits allows additional room on a disk to pack more data thus enabling high recording densities although superparamagnetic effect still persists.

Hitachi is one of the leading companies which is using this perpendicular recording technique. It expects improvement in read/write power consumption and the fastest power-on-to-ready time for immediacy of data delivery by 20-percent, the new drive to offer greater capacity with the lowest power consumption of any 1.8-inch hard drive, due in large part to a reduction of the disk spin-speed to 3600 RPM from 4200 RPM.

Now the only answer to this ever increasing need of space which is felt globally is we have to find a solution to superparamagnetic effect.

Future Looks Of MyComputer

Browser is heart of desktop or web application, it in a way helps organize stuff for us.When ever i hear the word "Tabbed", first thing which comes to my mind is "Mozilla".

Tabbed view in a way helps in organizing windows and it gives better look and feel to window manager. Tabbing nothing but a thread opened in same window.Tabs now are treated as new evolution of web browser. Soon after Mozilla many browsers have modified themselves with new avtar bringing in tabbed view.

With the same belief i made a project this summer vacation in which i tried to introduce tabbed view in Microsoft Windows file explorer. Some of the Features of this File Explorer are

• Tabbed View:- I enabled more than one instance of window to be opened within single instance of window.
  
• File Searching:-It has an option for searching with starting name or ending name of files, you can even search file with date of creation, to make search more specific you can even search files on content .
• Preview Contents:-Till now we had seen only image previews or may be vedios but how about having an option to view the contents of the file before even opening it, i have also embedded that into this small application of mine.
  
• Tree Structure:- It has the usual tree type exploring option which windows offer.

This was a small project which have implemented on Java platform using Swings. I would love to see in future these features to be embedded in Microsoft Windows. You can see some of the screen shots of my work by clicking on images above......

iRiver DP250

iRiver has introduced its first digital audio player in its Siren brand, which was announced earlier this year. The player is called the DP250-a potential competitor to the Sony NWZ-B100 MP3 Player.


Some of the Features with a difference in this device are:-

• It will be available in a 1GB and 2GB storage capacity
  
• It includes an FM tuner and a transmitter to broadcast your audio to any FM receiver - a really handy feature.
  
• The voice recording functionality appears to makes it a highly competent player.
• The device is capable of 18 hours of continuous audio playback.
  
• Featuring a 400mW mono built-in speaker, you can enjoy listening to songs that deliver high quality music.

Some changes which i would love to have in this player are

• The device should be equipped with some what bigger display.
• Some work is required on the size specification to make in look different.
  
• There should be some modification in display panel, i believe companies must give away with this traditional looking panels. Think about having a display similar to what iPod or maybe iPhone are offering.
• Another feature which could have made a difference is Wi-Fi support with the capability of downloading music from music stores.
  

iRiver DP250 DAP will carry a price tag of $85 (approx. Rs. 3,400) for a 1GB version and $120 (approx. Rs. 4,800) for 2GB.

Tribler :- Bandwidth as Digital Currency

A new Peer-to-Peer system called Tribler is into reckoning to overpower the existing unequal way of sharing. This system treats bandwidth as the digital currency which means the amount you are willing to spend, only that much amount of goods you can buy, rather you can say the amount of bandwidth you are willing to spend on uploading stuff or sharing, the same amount opportunity you will get to download in a Peer-to-Peer system. This is in a way an acknowledgment to selfless sharers and penalizing leechers who just like to download.

Currently this technology is being assessed by a European broadcasting body looking at ways of piping TV across the net. Which means your TV would be connected with internet and you can watch movies, listen to music and enjoy HDTV quality, but after you are done with watching your TV will start transmitting automatically for same amount of minutes as you watched.

Tribler is an open source Peer-to-Peer client, it's using the Python programming language it is possible to run on any Python supported platform. Some of the features of Tribler are

=>Tribler allows to group people with similar taste and tag them as friends.
=> You can import existing groups from programs like MSN and Gmail.
