Abstract
Abstract Storing data on a data processing system is done upon generation of a data file by displaying a user interface allowing user selection of storage criteria for the data file. Responsive to user selection of storage criteria for a file determining a physical format type for the file from a plurality of available physical format types. Then the file is stored on a direct access storage device as at least a first record conforming with the determined physical format type.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
83 words
A data processing system, comprising: a direct access storage device; means for generating data files; a user interface allowing user selection of storage criteria upon generation of a data file; means responsive to user selection of storage criteria for a file for determining a physical format type for the file from a plurality of available physical format types; and means for storing the file on the direct access storage device as at least a first record conforming with the determined physical format type.
Claim 2
Dependent Claim
39 words
The data processing system of Claim 1, wherein the direct access storage device is a constant angular velocity disk drive and the available physical format types are a plurality of data track bands written at differing write clock frequencies.
Claim 3
Dependent Claim
39 words
The data processing system of Claim 1 or 2, wherein the means for storing the file on the direct access storage device writes records to data track bands having a write clock frequency meeting the user selected storage criteria.
Claim 4
Dependent Claim
23 words
The data processing system of Claim 1, 2 or 3 wherein the plurality of physical format types include spiral and concentric data tracks.
Claim 5
Dependent Claim
37 words
The data processing system of Claim 1, wherein the direct access storage device is a disk drive and a physical format type includes a characterization as an inward spiral, an outward spiral, or a concentric data track.
Claim 6
Dependent Claim
20 words
The data processing system of Claim 5, wherein a physical format type includes a characterization of track to track pitch.
Claim 7
Dependent Claim
19 words
The data processing system of Claim 6, wherein a physical format type includes a characterization of write clock frequency.
Claim 8
Dependent Claim
65 words
The data processing system of Claim 7, wherein the disk drive comprises a plurality of disks having two major surfaces each for storing data, the major surfaces of the disk drives having corresponding addresses differing only a variable relating to the particular surface, characterization of a physical format type for a file allowing alternation of inward and outward spirals from major surface to major surface.
Claim 9
Dependent Claim
12 words
The data processing system of Claim 5, wherein spirals are track interleaved.
Claim 10
Dependent Claim
20 words
The data processing system of Claim 8, where in a plurality of physical format types occur on one major surface.
Claim 11
Dependent Claim
53 words
The data processing system of Claim 9, wherein the means for storing includes: a buffer between the direct access storage device and the means for generating data files for compensating between differentials in data rates; and means for back accessing tracks on the direct access storage unit for compensating between differential data rates.
Claim 12
Dependent Claim
29 words
The data processing system of Claim 1, w herein the direct access storage device includes: a plurality of surfaces; and a plurality of corresponding spiraled tracks on each surface.
Claim 13
Dependent Claim
19 words
The data processing system of Claim 12, the corresponding spiraled tracks being recorded with different views of a scene.
Claim 14
Dependent Claim
23 words
The data processing system of Claim 1, wherein the plurality of available physical format types includes: at least a first spiral type track.
