AI Technical Summary

Problems solved by technology

[0006] However, the main disadvantage of this traditional "squeeze" method is that the wobble increases the probability of overwriting adjacent data tracks during reverse writing
Therefore, during readback, even if the head follows the servo track, errors can occur due to the wobble of the track being written to the data and wobble inherent during readback, and can be even worsened by a wobbling servo track
The described error may cause a particular reader to read two or more tracks at the same time, especially when the tracks are closely spaced or overlap
Synthetic signal is noisy and makes data extraction impossible

Embodiment Construction

[0022] The following description is of the best mode currently contemplated for carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and is not meant to limit the inventive concepts claimed in the present invention. Furthermore, certain features described herein may be used in combination with other described features in every possible combination and substitution.

[0023] Figure 2 illustrates a module 200 carrying a plurality of reading devices (also referred to as readers, sensors, read elements, etc.) and writing devices (also referred to as writers, write elements, etc.). The writing device 201 and reading device 202 are positioned towards the middle of the module 200 as shown. To enhance the stability of the module 200 for proper use, the module 200 is mounted to a beam 206 formed of some rigid material. Such beams 206 are often referred to as "U-beams". A cover plate 208 is also often installed d...

Abstract

A tape head system with a plurality of readers, wherein the width of the reader is less or equal to the half width of the writer or the data track. The readers are aligned with each other along the width direction of the track. The data tracks and the conduction band are used in track tracking, according to one preferred embodiment, additional reader is used to read the servo band for tracking.

Description

technical field [0001] The present invention relates to tape drive heads, and more particularly, the present invention relates to an array of read and write devices wherein the read devices have a width that is smaller than the width of the write devices or data tracks. Background technique [0002] Data is stored on magnetic media such as magnetic tape by writing the data in a number of linear tracks. The tracks are divided in a direction transverse to the tape, and a given track extends longitudinally of the tape. [0003] In order to increase the amount of data that can be written for a given tape width, considerable efforts have been made to place data tracks adjacent to each other. The most common method for writing is to use writers separated by a predetermined distance. During writing, multiple tracks are written simultaneously, with each track having a gap between it and its adjacent track. Then, when writing in the opposite direction, the head steps in to one sid...
