Abstract

Highly accessed data (i.e. Volume Table of Contents VTOC) is cached today in RAM. This invention is to physically write a second (or more) copy of frequently accessed data repeatedly around the circumference (and/or radius) of the disk to allow faster access, when requested by the system. With the additional option to find data at a closer location the system performance can be improved. A second benefit is that the wear of the disk due to the head flying over it repeatedly in an area like VTOC can be reduced. A third benefit is that the data is backed up in the case of data loss. 1

Physical Caching System for Improved File Performance

   Highly accessed data (i.e. Volume Table of Contents VTOC) is cached today in
RAM. This invention is to physically write a second (or more) copy of frequently
accessed data repeatedly around the circumference (and/or radius) of the disk to
allow faster access, when requested by the system. With the additional option to
find data at a closer location the system performance can be improved. A second
benefit is that the wear of the disk due to the head flying over it repeatedly in
an area like VTOC can be reduced. A third benefit is that the data is backed up
in the case of data loss.
