[3] Bajorek joined IBM Yorktown in 1971 becoming part of the research effort led by David Thompson and Lubomyr Romankiw studying readback devices based on magnetoresistance.

[7][8] The point-of-sale hand-held magnetoresistive transducer represented the first commercialization of the effect discovered by Lord Kelvin in 1856.

Based on this experience, Bajorek established the Advanced Packaging Technology Laboratory (APTL) and was appointed its first director in 1980.

The APTL and MRI collaborations were among the first of eventually 19 joint programs at IBM specifically instigated by Ralph Gomory and designed to bridge between the Research and the Development organizations.

In 1996, Bajorek retired from IBM and joined Komag, Inc.[19] in San Jose, California, as executive vice president of advanced technology.

[21] He has also been an expert witness in several cases notably the patent infringement brought by Carnegie Mellon University (CMU) against Marvell Technologies that resulted in a $750 million settlement.

[22][23] Bajorek is a member of the Storage Special Interest Group at the Computer History Museum, Mountain View, California.

At issue were whether Komag was a competitor or supplier to IBM and whether the non-compete clause could be enforced under California State law.

[24][25][26][27] Only three people have won both the Millenium medal and the Johnson award: Charles Denis Mee, Mark Kryder, and Christopher H. Bajorek.
