Country flows data tracks investment allocation and flows in funds covering stock markets in developed and emerging countries.
Time-Based servo bands, which are written to tape during the manufacturing process, are used as a reference to position all data tracks for the life of the cartridge.
The common method of creating servo-positioning tracks on the tape is to embed magnetic servo tracks between the data tracks on the recording surface, reducing the physical space available to write data.
Tape media and cartridges have changed dramatically over the years, as improvements continue to be made across virtually every physical parameter of tape from the thickness of substrate and magnetic layers, size and density of magnetic particles, track width and number of data tracks, to the length and speed of the tape within a cartridge.
In the case of SDLT 320, there are 448 serpentine data tracks across the half-inch tape, compared to 512 tracks with the LTO Ultrium 2 format.
The servo signal is a series of sine waves that provide precise feedback to control the position of the read/write head on each of the 384 data tracks across the width of the tape.
Linear tape technology utilizes a recording method in which the data tracks are written in a linear pattern on the tape.
