Estimating the term…
A data accessing process with multiple read pick-up heads and/or multiple read/write heads and, where each head along with its independent control circuit can independently access the same data, concurrently, and read out different parts at the same or different times. The most important fields for my multiple, concurrent, separate access process are DVD, LAN and other storage systems, and Internet servers where data that is frequently accessed and often long, so that the server is tied up for long periods of time. THE PROBLEM THIS PROCESS IS MEANT TO ADDRESS IS, SIMPLY, CONCURRENT, MULTIPLE REQUESTS FOR PARTS OR ALL OF THE SAME DATA. This patent also addresses three other problems: the process of controlling the multiple pick-up heads, the location and the arrangement of the pick-ups, and the design of the pick-ups, such that they can be arranged as closely as possible, thus increasing the number of pick-up heads per disc.
1) A process for, concurrently, storing and accessing video data for different requester, reading out different parts, and having different starting times and where multiple users can access the same data concurrently
2) Transducers arms for the arrangements of the arms where the pivots are in a circle beyond the disc area where the transducer arms with the transducers will be as thin as possible and will be TILTED TOWARD THE DISC SURFACE AT AROUND A 30 DEGREE ANGLE FROM THEIR PIVOT so that though the coverage areas overlap, but neither the transducers nor the arms will physically collide.
