Abstract

Surface Visualizer is a tool for use by engineering, product assurance, and manufacturing to process the manufacturer's defect data for high-capacity, fixed disk drives. The graphic capabilities of a personal computer high-resolution color display are used to present surface defects in a graphic form. The primary method of display is a scale representation of a disk surface with all defects occurring on that surface in a highlighted color.

Surface Visualizer - Calculate Feature

Surface Visualizer is a tool for use by engineering, product assurance, and manufacturing to process the manufacturer's defect data for high-capacity, fixed disk drives. The graphic capabilities of a personal computer high-resolution color display are used to present surface defects in a graphic form. The primary method of display is a scale representation of a disk surface with all defects occurring on that surface in a highlighted color.

The operating systems that use the finished product address the surface only in "logical sectors" that increase from 1 to the capacity of the file. In many instances, it is desirable to find the physical defect that is associated with an error that has been detected by the operating system in a logical sector. At other times, it may be desirable to find out what logical sector(s) are associated with an error that is observed when using the Surface Visualizer.

The calculator feature can be used at any time the Visualizer is active. The user is first asked to choose whether a "Logical->Physical" or "Physical->Logical" conversion is desired.

If the chosen conversion is Physical->Logical, the user is prompted to enter the logical sector. The logical sector calculation is then displayed. Following that, the appropriate surface is displayed with the sector display turned on. The calculated sector pieslice is
