TH99657A - Tools and methods of testing data construction; Analysis of Data Tests and Testing of Storage Disc Media And / or read / write head - Google Patents

Abstract

DC60 has disclosed the tools and methods for the construction of the test form analysis of the data. And the storage disc media test And / or read / write head in the desired artifact A method of creating a test form has been disclosed of the data to be written down. Storage media (4) disc for testing The method will consist of Disc rotation (4) Detection of disc rotation speed fluctuations (4) Generation of a reference clock signal (53) According to such fluctuations to cause rotation simultaneously with the rotation of the disc ( 4) and test pattern generation of data (58), using the aforementioned clock signal (53) as a timing reference, tools and methods of test form generation of test data analysis data were disclosed. And the storage disc media test And / or read / write head in the desired artifact A method of creating a test form has been disclosed of the data to be written down. Storage media (4) disc for testing Methods include: disc rotation (4) detection of disc rotation speed fluctuations (4) generation of a reference clock signal (53) according to such fluctuations to achieve simultaneous rotation. With the rotation of the disc (4) and the generation of the test pattern (58) using such a reference development signal (53) as a timing reference:

Claims (2)

1. a method of creating a test pattern of data to be written to the storage disc storage media. For the test Methods that include: disc rotation; Detecting fluctuation of Disc rotation speed; Generating a reference clock signal based on loud fluctuations It is said to coincide with the disc rotation and the construction of a test of the data. By using the said reference clock signal as a reference for timing 2. Methods according to claim 1, where this fluctuation detection process includes: Multiple mark detection at the tag:
