DESCRIPTION:For nearly a century\, magnetic audio tapes have preserved a w
 ealth of valuable information\, from historic broadcasts to timeless music
 \, capturing a significant part of our cultural heritage. Over time\, tape
 s deteriorate and suffer various types of damage\, leading to the loss of 
 valuable information. It&#x27\;s crucial to develop methods for digitizing
  these damaged tapes without causing further damage. Tunnel Magnetoresista
 nce (TMR) sensors\, combined with a custom setup\, are ideal for this appl
 ication due to their high sensitivity\, room temperature operation\, and m
 icrometric spatial resolution.\\parTo understand the tape&#x27\;s magnetic
  field\, simulations were conducted using finite model methodology and ana
 lytical analysis. Multiple versions of sensor probe designs were developed
  to verify the setup&#x27\;s accuracy\, optimize the sensor-to-PCB integra
 tion process\, and utilize insights from the simulations. Measurements wit
 h each sensor version were performed using a custom-built setup and softwa
 re. The evolution between versions yielded promising results and enhanceme
 nts\, pinpointing key areas for progress in future iterations.
