Tele-File system for automatic location of files on tape
For fast access to individual files, the e-VTR must know their precise location on tape. The e-VTR uses the Tele-File system to achieve this. Tele-File cassette labels contain a memory chip onto which data can be written and subsequently read. This read/write process is achieved using a non-contact reader/writer that is built into the cassette compartment of each MPEG IMX VTR. During the recording of an incoming file, the e-VTR writes its IN and OUT point to the Tele-File label on the MPEG IMX cassette.
If this tape is subsequently used in another e-VTR, the e-VTR reads the Tele-File label and immediately knows the IN and OUT point of every file on the cassette.
Tele-File labels can be purchased in batches of 100, and can be attached to any Betacam-family cassette.
