Dual Circuit Isolation of Writer to Reader Crosstalk for SGV Modules - A simplified explanation of the abstract

This abstract first appeared for US patent application 18227510 titled 'Dual Circuit Isolation of Writer to Reader Crosstalk for SGV Modules

The abstract of this patent application describes a tape head and tape head drive that includes a tape head with same gap verify (SGV) modules to reduce cross-talk between write and read transducers.

• The tape head includes SGV modules with write and read transducer pairs.
• Each write transducer is connected to writer bonding pads via writer leads, and each read transducer is connected to reader bonding pads via reader leads.
• An isolation shield is placed between the write and read transducers to act as a Faraday cage and reduce cross-talk.
• The SGV module can write data to a tape using the write transducers and verify the data using the read transducers simultaneously.

Potential Applications: - Data storage systems - Magnetic tape drives - Information archiving

Problems Solved: - Cross-talk between write and read transducers - Data verification accuracy

Benefits: - Improved data writing and reading accuracy - Reduced interference between transducers - Enhanced data storage reliability

Commercial Applications: Title: Advanced Tape Head Technology for Data Storage Systems This technology can be used in data centers, archival facilities, and other industries requiring high-capacity data storage solutions.

Questions about Tape Head Technology: 1. How does the isolation shield reduce cross-talk between write and read transducers? The isolation shield acts as a Faraday cage, blocking electromagnetic interference between the transducers.

2. What are the main advantages of using SGV modules in tape heads? SGV modules improve data writing and reading accuracy while reducing interference, leading to more reliable data storage solutions.

Original Abstract Submitted

The present disclosure generally relates to a tape head and a tape head drive including a tape head. The tape head comprises at least one same gap verify (SGV) module comprising a plurality of write transducer and read transducer pairs. Each write transducer is coupled to writer bonding pads via writer leads, and each read transducer is coupled to reading bonding pads via reader leads. An isolation shield is disposed between the write transducer and read transducer such that the isolation shield is disposed between each writer lead and each reader lead. The isolation shield acts as a Faraday cage to reduce cross-talk between the write and read transducers. The SGV module is configured to write data to a tape using the write transducers and read verify the data written on the tape using the read transducers such that the write transducers and read transducers are concurrently operable.
