IBM, Seagate and HP combined their efforts and engineered a new innovative LTO technology that offers a viable and ideal storage medium in a growing complex of backup data storage options. IBM LTO-3 tape has established new standards for performance, capacity and data throughput. Exceptional compatibility of high capacity IBM LTO3 tape enables the users to interchange their sensitive data across different platforms. Increasing needs of the modern backup applications are efficiently accommodated by the new advanced IBM LTO-3 media format. 24R1922 is the part number of the highly economical IBM ultrium 3 cartridge whose native capacity is 400 GB. The compression ratio offered by the IBM LTO-3 is 2:1. This means that the data recording capability of IBM LTO-3 tape will be twice as that of its native capacity.

Ultrium is a powerful and high capacity specification of linear tape open whose per cartridge native capacity offerings range from 100GB (LTO-1 media tape) to 800GB (LTO-4 tape). High performance LTO-3 tape products developed by IBM are carefully engineered to meet the organizations’ needs at an affordable cost. The design of IBM LTO-3 tape comprises of a single hub that allows optimized packaging of media within the ultrium cartridge.

IBM has developed an exceptional and reliable compression algorithm for the LTO-3 tape format which doubles its speed as well as its data capacity. The data tracks of the IBM 24R1922 tape are further divided into 4 areas. Each area is called “data band”. Servo information bounds the top & bottom of each data band. Data is written on each data bands of IBM LTO-3 tape media one at a time. Cartridge memory is unique feature included in the IBM LTO cartridges. Upon loading the tape into the drive, it reads the contents held in the 4KB cartridge memory to accelerate its performance and upgrade the data throughput. The cartridge memory is non-volatile and is embedded in the robust cartridge shell of IBM LTO-3. Users of IBM LTO tape format are offered more luxury as they do not have to insert the cartridge into the drive for retrieving the information about initialization, manufacturer’s data, and calibration information.

Dedicated dual servo mechanism of IBM ultrium-3 increases the data integrity. IBM LTO-3 ultrium technology features error correction system which comprises of 2 levels. This error correction system is very effective and recovers the information from the longitudinal scratches. When the LTO data tapes are being manufactured, the servo bands are recorded onto the media tape. If any of the elements of servo becomes corrupt or defective, the head of the tape drive continues to track because of the 2nd redundant servo mechanism. The servo frame in IBM LTO-3 ultrium format encodes the words in longitudinal position which enables the data administrators to retrieve information from the absolute areas along the entire tape’s length.

Toshiba, Matsushita, SanDisk and many other major original equipment manufacturers of mobile communication founded the secure digital card association. New generation cellular phones are incorporated with advanced features such as MP3 players, cameras, internet messaging and exciting multimedia capabilities. All these latest features have increased the demand for fast and high capacity flash storage cards. Manufacturers of cellular phones are looking forward to find out new ideas to boost the replacement cycles among the consumers. While on the other hand cellular service providers are putting in more efforts to accelerate the adoption of latest applications by their customers. High resolution mega pixels digital cameras have elevated the need for high capacity memory cards. This new emerging market boosted the sales of mini-SD memory cards.

Secure digital controller and NAND flash technologies are utilized by SanDisk in the new mini-SD card format. MiniSD memory cards have gained more success and popularity due to their exceptional compatibility and reliability. SanDisk started shipping the mini-SD memory cards in March, 2003. Mini SD card is an advanced form of the reliable secure digital SD card standard. The target of the mini SD memory cards are the new generation 3-G and 2.5-G cellular phones that provide storage intensive attributes like video capture, video games, voicemail, PIM (personal information management), MP3 players, digital cameras and E-mail capabilities. Significant savings are offered by the SanDisk mini-SD memory card in card volume and area. Volume and area are the 2 critical parameters of the memory card’s design for the new advanced versions of cellular phones and digital cameras. More than 60 percent volume and 40 percent printed circuit board are saved by the miniSD memory card in comparison to the standard SD memory cards for supporting the memory card in portable device.

MiniSD card form factor has provided more flexibility and freedom to the designers of cellular phones and digital cameras in fitting a card slot in their devices. Mini-SD card format offers more benefits to its consumers as they can transfer their data between cellular phone (miniSD equipped) and other secure digital compatible host, like laptop PC, PDA or digital camera. Software and electrical compatibly of SanDisk miniSD flash card with the existing secure digital standard makes it more advantages and the preferred choice of the consumers.

When the AIT tape cartridge is inserted into the tape drive, the tape drive components pull out the tape reel and wrap it around the tape head. Ampex invented the heliacal scan mechanism in 1956. It was the faster recording technique and had the sufficient storage capability. Therefore it was mainly used for recording TV programs. Diagonal track and rotating head in AIT tape format result in slow traveling tape which speeds up the transfer speed. The AIT tape drive pulls the tape reel from the cartridge and afterwards it is wrapped around the tape head.

In helical scan, the tape reel moves at a slow speed but the tape head moves at a fast speed. The tape head is tilted in the AIT tape format which brings a new tape area into play along with each tape head’s rotation. Signal’s each segment is recorded across the tape reel as a diagonal stripe. In helical scan mechanism, the circular drum wraps the AIT tape’s reel at an angle and records the information onto the media with increased level of reliability and accuracy.

Helical scan is also used by digital audio tapes (DAT) and Mammoth-2 tape format for data reading and recording. AIT backup tape format is most cost efficient for mid-range tape market. It is more robust, powerful and reliable tape medium that other tape formats. AIT has become the most popular tape format that ensures fast data searching and unmatched data reliability with high level of data throughput. AIT backup tape is the most efficient and smartest choice for tape automation and stand alone working environments. All the versions of AIT backup tape deliver unparalleled performance and outstanding durability to protect the precious data for longer time periods. The WORM technology adds to the data security features of AIT tape storage format resulting in prevention of data deletion and alterations. WORM functionality is the reliable feature incorporated in AIT which protects the customer’s data.

Data searching speed has been boosted in the AIT format enabling it to save time and cost. The memory in cassette (MIC) contributes to fast searching. The MIC functions as a data index in AIT tape format. MIC technology has also contributed in reducing media load times leading to improved efficiency. The native speed and capacity of AIT-2 drive is 6 MBps and 50GB respectively. AIT is the best backup solution in terms of durability, data reliability, storage capacity and media stability. The smooth tape surface enables error free data writing at a fast transfer rate.
