Sony AIT3 WORM format satisfies the requirements of SEC (Securities and Exchange Commission) efficiently and is ideal and reliable choice for dealers and brokers of securities market. Sony AIT-3 assures cost effective and secure storage of the electronic data. Sony has made sure that all the necessary technologies and features are added to the AIT3 WORM tape format so that it can satisfy and surpass the technical & legal demands and requirements of the dealer-broker industry.

Cohasset (Cohasset Associates, Inc.) is ranked as the topmost in management consultancy and are expert in information management (document based). Cohasset evaluated the results of AIT3 cartridge used in the tape drive of Sony AIT WORM to match the performance and features of the AIT-3 tape technology with the SEC identified requirements of data records and retention. The findings of the Cohasset showed that the AIT3 WORM cartridge satisfied both the SEC regulation 17a-4's spirit and letter.

AIT3 tape technology enables the retention of data on media which is non-erasable and also non-rewritable at the same time. AIT automatically verifies the accuracy and quality of the data storage procedure which is the requirement of 17a-4. AIT WORM technology efficiently meets the requirement of download ability of records and index, date-time recording and serialization. These results are the result of the various technologies featured in the Sony AIT-3 cartridge such as the introduction of write once read many ECC (Error Code Correction) technology and RMIC (remote memory in cassette). Recording enable hole has been removed from AIT cartridge and the erasure head is removed from the tape drive. Other different technologies are also added to the AIT-3 tape technology to protect the recorded information form unintentional or intentional modifications after recording.

Before the process of recording begins, the verification of the AIT WORM cartridge is done by the AIT tape drive. If the tape drive identifies the tape cartridge as AIT WORM, then after passing several other additional tests the writing of data will be enabled. Information of the identification between storage media and the Remote MIC chip is confirmed by the AIT WORM. Assuming that the pre recording session was successful, the last group count is organized which is then searched along with EOD (end of data) by the AIT-3 tape drive. Writing is then allowed by AIT3 on the maiden space followed after the pre recording of Last Group Count (addition of one) or the end of data. The data tape becomes read only and further recording of information is not allowed by the AIT3 tape drive if recording process fails and the EOD (end of data) is not recorded.

Tape drive of AIT WORM is designed specifically as the erase head is excluded. Therefore in this way the erasure of recorded data on AIT-3 tape cartridge either unintentionally or intentionally is precluded. Requirement for the format of non erasable & non rewritable is effectively met by the AIT-3 media technology. These requirements are met by AIT through different new safeguards like the over writing is preempted due to the communication between the embedded software in the AIT tape cartridge and the AIT3 tape drive's hardware.
