Abstract

The methods and factors described will record the sample arc. Servo into a magnetic plate (Or record a portion of the servo sample to tape) at equal distances on the groove assigned to it. And will read the curves of these servo samples (or parts of the servo samples) while performing the task of searching, calming and following the grooves. A method used to determine the distance in time that can be allowed between the arcs. Of servo samples (Or part of the servo sample), parts on the groove and length Of any part of the data involved, such as a curve or a record of information containing Different lengths that the magnetic disk or tape can accommodate. Will make the arc Of servo samples (Or part of the servo sample) that are evenly spaced on the groove. Assigned to each part within the data area of the data arc. Or is inside the flesh That of the identification number Or next to the location marker (For example, a machine (Position or index mark), the sampling rate from the servo sample arc (or servo sample segment) is constant and independent of the number and length. Of payload Because of such independent relationship This method is suitable to It is used for recording in constant linear density. In a magnetic disk that is organized into strips and uses the arc of a servo example, for example, conventional fixed space divider architecture and even non-arc architecture such as Such as the architecture in the arrangement Divides the key-counting area where data is recorded in a long log of data. Different Including in a tape drive device that uses fixed space allocation architecture. Or a data-counting form as well
