AIT tape cartridge has application-ID which is written on its? system area. By reading the application-ID, the AIT WORM drive is able to identify if the AIT tape media is WORM or non-WORM media. If the application-ID is somewhat corrupted, even then the AIT drive will not overwrite as it does not has the recording enable-hole. Verification process is conducted by the AIT WORM-drive that matches the RMIC's application-ID with the AIT data tape's system area application ID. The storage media is rejected if there is a mismatch between these two application IDs.
?Error Code Correction? in the AIT3 WORM technology offers improved error correction process. Error correction in AIT technology comprises of 4 distinct levels. The first level is called ?pre-Error Code Correction? while the other 3 are the ECC ?Error Code Correction?. First correction level involves the non Error Code Correction components that occur before the compression of data and the errors are addressed at bit-level. If the error cannot be resolved by the non-ECC component, then the data is sent back to the host system for resolution. Recording process terminates if the host system is unable to resolve the data error.
The other error correction levels (ECC) in AIT3 WORM cartridge are more advanced & comprehensive that work at the byte level. As the process of pre-ECC completes then the data moves through the other 3 correction levels. The process will terminate if errors are detected. Further recording will not be allowed until the host system finds the solution and removes the error. Sony AIT cartridge's recording procedure guarantees the accuracy of information being written onto the tape media.

During the read/write method of Sony AIT technology, the data from host is sent to SCSI-chip and then from there it moves to the I-F buffer, and at the end this data is sent to data-compression chip. In the pre-ECC procedure, the information is recorded onto the media with the addition of parity at bit-level in order to assure accuracy. All the conflicts and errors that cannot be resolved by adding parity is sent back to host for solution and verification of data accuracy. All this process is carried out before the next phase of the procedure continues in which the AIT technology's ECC-component detects errors and analyzes parity at byte-level. If data is returned to the data-compression chip before the ECC component or to the host after the pre ECC component, and the identified errors can not be resolved, then the process of recording terminates automatically.
Unique serial number is given to each AIT WORM cartridge which is saved in RMIC (Remote MIC) header. During the assembling of the AIT data tapes at the manufacturer, this unique number is saved in the AIT tape's application ID and in the RMIC as well. This unique number comprises of thirty two digits.
Application software is required by the AIT WORM functionality and the tape drive. Application software time stamps the information that is being written of AIT3 WORM tape. So this helps in indication of the date and time of data recording.

Organizations around the globe now require high speed and cost effective tape storage with greater capacity that have the capability to backup & handle large data volumes and storage intensive information. New backup tape storage standards have been unveiled by Sony Corporation in order to meet the increasing demands of businesses around the world. The latest innovative high density, durable and fast speed tape storage format developed by Sony is the AIT (Advanced Intelligent Tape).
Sony Corporation is considered as the leading innovator in the technology of high density recording media. High durability is achieved in the AIT tape format by the use of Sony's AME technology. AME technology is the outcome of the vast experience of Sony related to the magnetic tape media. Sony has been strongly committed to the technological excellence. The hallmarks of the Sony Corporation are the commercialization and development of new advanced mechanisms and techniques of data tape media.

AIT cartridges include MIC (memory in cassette). This MIC chip helps in immediate and direct connection is provided to the on-board processors of AIT tape drive. So with the assistance of MIC chip, the AIT tape drive can quickly load the AIT media and the data managers are provided with fast access to the user-files. The MIC provides multiple on tape loading & unloading points. MIC chip holds wealth of information related to the current state and history of the AIT data cartridge. MIC chip provides numerous advantages in the Sony AIT tape format. It provides faster access speed. Without MIC chip, the load acceleration is about 20 seconds, and unload acceleration is about 27 seconds. With the inclusion of MIC chip in AIT tape cartridge, the load acceleration and unload acceleration are reduced to <10 seconds and 17 seconds respectively. The search speed acceleration in the AIT tape format ranges from 225 to 450 MB/sec. The average time of file accessing has been improved in the AIT tape format to less than 27 seconds with the addition of MIC chip. Without MIC the average access time was 57 seconds. Tape4backup dot com is offering lifetime warranty and cheapest prices on all media tapes especially AIT, LTO, DLT, Travan, VXA and Super DLT tapes.
Different information is stored in the MIC chip that includes data record during manufacturing time, information regarding data writing when the tape cartridge was first inserted into the tape drive, updated portions that are the part of write, read or load sequence, and the portions which are directly recorded by the user applications. The information about media history is also written in the MIC chip. The data access is also improved in the Sony AIT format. All the information that has been recorded in the MIC chip enhances the sub-systems of tape format and provides more benefits to its users.
