Summary :

Failure analysis is performed without having to pull the tape out of the cassette. This can be achieved by using an IBM* LTO tape drive (LTO stands for Linear Tape Open) and a specific optical setup which allows to perform failure analysis of the defective tape within the drive.

    Along with the optical setup with the desired optical properties, a specific fixturing is required to accept and position the tape drive so the tape can be inspected for typical defects like scratches, inclusions and contamination .

  The advantages of the described system are : the tape remains within the drive in a controlled environment eliminating any additional handling-related damage or contamination defective tape locations can be positioned automatically (this feature is being provided by the drive control software) and do not have to be searched and located manually failure analysis can be performed in a significantly reduced timeframe visual detection of defects is more effective in case tape is presented on a curved surface (as in the drive spool) instead of a flat surface in case desired, an automated image analysis system or laser surface scan system can be integrated into the system to eliminate manual visual inspection

Description:

    Basic idea is to use a standard tape drive for the handling of the tape, which - by design - provides visual access to the tape defect location, combined with an optical setup to directly inspect the tape within the drive.
