===Tape recorder anomaly===
The failure of ''Galileo''{{'s}} high-gain antenna meant that data storage to the tape recorder for later compression and playback was crucial in order to obtain any substantial information from the flybys of Jupiter and its moons. The four-track, 114-[[megabyte]] digital tape recorder was manufactured by [[Iteris|Odetics Corporation]].<ref>{{cite web |url=http://www2.jpl.nasa.gov/galileo/faqtape.html |archive-url=https://web.archive.org/web/20090403160253/http://www2.jpl.nasa.gov/galileo/faqtape.html |archive-date=April 3, 2009 |title=''Galileo'' FAQ – Tape Recorder |publisher=NASA/Jet Propulsion Laboratory |url-status=dead |access-date=May 15, 2011}}</ref> On October 11, it was stuck in rewind mode for 15 hours before engineers learned what had happened and were able to send commands to shut it off. Although the recorder itself was still in working order, the malfunction had possibly damaged a length of tape at the end of the reel. This section of tape was declared "off limits" to any future data recording, and was covered with 25 more turns of tape to secure the section and reduce any further stresses, which could tear it. Because it happened only weeks before ''Galileo'' entered orbit around Jupiter, the anomaly prompted engineers to sacrifice data acquisition of almost all of the [[Io (moon)|Io]] and [[Europa (moon)|Europa]] observations during the orbit insertion phase in order to focus on recording data sent from the atmospheric probe during its descent.<ref>{{cite press release |url=https://www.jpl.nasa.gov/news/galileo-on-track-after-tape-recorder-recovery/ |title=Galileo on Track After Tape Recorder Recovery |publisher=NASA/Jet Propulsion Laboratory |date=October 26, 1995 |access-date=January 19, 2021 |archive-date=November 30, 2021 |archive-url=https://web.archive.org/web/20211130055714/https://www.jpl.nasa.gov/news/galileo-on-track-after-tape-recorder-recovery |url-status=live }}</ref>
