Magnetic storage

The search results provide excellent information for external links:

• External Link 1 (History): The Computer History Museum has a page on the "First commercial hard disk drive shipped" (IBM Model 350).¹⁶ This is perfect.

  • URL: https://computerhistory.org/blog/1956-first-commercial-hard-disk-drive-shipped/ (This is the actual URL from the snippet after redirect, not the Google search proxy URL.)

• External Link 2 (Regulatory): Multiple sources discuss SEC record retention requirements, specifically SEC Rules 17a-3 and 17a-4. I'll pick a general explanatory one or one directly from SEC if possible, but the search results point to articles summarizing them which is acceptable if they cite the rules correctly. InnReg¹⁵ and Thomson Reuters Practical Law¹⁴ seem good. I'll use InnReg as it gives clear details.

  • URL: https://www.innreg.com/sec-rule-17a-4-compliance-essentials-for-record-keeping/

• External Link 3 (Data Storage Trends/Financial Industry): Invesforesight¹³ and Forbes¹² discuss data storage trends in the financial sector. Invesforesight seems more focused on the financial sector's data storage specifically.

  • URL: https://invesforesight.com/data-storage-in-financial-sector-new-trends/

• External Link 4 (Long-term Archival/Critique): Komprise¹¹ and Stellar Data Recovery¹⁰ discuss magnetic tape for long-term archiving, which is a key application of magnetic storage. Source⁹ mentions that it is "probably unwise to depend on magnetic tape as a reliable long-term storage method for valuable data" in some contexts, offering a critical perspective. Stellar Data Recovery⁸ gives a balanced view on its resurgence and advantages. I'll go with Stellar Data Recovery for its detailed explanation of magnetic tape's role in enterprise archiving.
