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 - Listing 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 manufacturer provides a list of the defect areas on the disk surfaces, both as a printed listing and as special records on the disk surfaces. These listings order defects in physical order. It is difficult to determine defect-related groupings by examination.

The listing program displays defects in related groupings using character color and spacing to separate related defect groups. The program starts with the first defect on a surface and repeatedly applies a grouping algorithm to the defect list. When no more related defects can be found, the program changes the character color and starts a new group. If the listing is near the screen bottom, the listing program suspends listing and waits for a user keystroke before proceeding. When no defects remain in the original list, the listing program concludes.

The Visualizer program accepts defect data for a variety of disk types. The program chooses the appropriate grouping algorithm depending on surface density, as indicated by number of tr...
