Hard Disk Dri, er, Connive: Two sales execs accused by Uncle Sam of bumping up HDD component prices

Japanese supplier's biz model, like its products, were straight as a spring

Two former sales executives at NHK Spring Ltd, Hitoshi Hashimoto and Hiroyuki Tamura, were indicted in America last week for alleged participation in a worldwide conspiracy to fix the prices of hard disk components.

"This charge demonstrates that antitrust violations are not just corporate offenses but also crimes by individuals," said assistant Attorney General Makan Delrahim. "The [US Dept of Justice's] Antitrust Division is committed to prosecuting culpable senior executives who circumvent the antitrust laws in order to cheat consumers."

The indictment [PDF] against the pair, filed in a federal district court in San Francisco, California, follows a guilty plea from the Japan-based manufacturer last year. The industrial spring maker agreed to pay a $28.5m fine for participating in an eight-year-long scheme to collude with competitors to fix the prices for hard disk drive (HDD) suspension assemblies.

Suspension assemblies hold the HDD recording head near the spinning disk so digital information can be magnetically written and read. They can be sold as standalone components or as part of an HDD in a computer, game console, printer, and so on.

Following NHK Spring's admission of guilt, class-action civil lawsuits were filed in Detroit and San Francisco against the alleged corporate co-conspirators, a group said to include buyers of these parts: Hutchinson Technology (Minnesota), Magnecomp Precision Technology (TDK subsidiary in Thailand), NAT Peripheral (Dong Guan, China and Hong Kong), NHK International Corporation (Michigan), NHK Spring (Thailand), NHK Spring Precision (Guangzhou, China), SAE Magnetics (Hong Kong), and TDK Corporation (Japan).

Investigations into hard disk price fixing by US and Japanese authorities have been underway since at least 2016, when Japanese authorities raided the offices of NHK and TDK. Two years later, the Japanese Fair Trade Commission issued a cease-and-desist order to both companies, having determined that they colluded to set prices.

In 2018, Brazil's antitrust authority announced an investigation of five companies – Hutchinson Technology, Magnecomp Precision Technology, NHK Spring, TDK, and SAE Magnetics – and 38 individuals over allegations the firms divided the market up among themselves and set prices.

Over the past two decades, allegations of price fixing have been leveled against manufacturers of many different types of computer components, including DRAM, SRAM, optical disk drives, LCDs, capacitors, resistors, inductors, and the like. Collusion to sustain prices appears to be a common though illegal way companies try to survive when their products become commodities.

Tamura served as general manager of NHK's disk drive component sales division from approximately 2007 to 2013; Hashimoto occupied the same role from 2013 through 2016. The two Japanese citizens, if convicted in the US, face up to 10 years in prison and a fine of up to $1m, though it could be more if their personal gain or any victim's loss exceeds that amount. ®

    On Call Let us take a little trip back to the days before the PC, when terminals ruled supreme, to find that the more things change the more they stay the same. Welcome to On Call.

    Today's story comes from "Keith" (not his name) and concerns the rage of a user whose expensive terminal would crash once a day, pretty much at the same time.

    The terminal in question was a TAB 132/15. It was an impressive bit of kit for the time and was capable of displaying 132 characters of crisp, green text on a 15-inch CRT housed in a futuristic plastic case. Luxury for sure, unless one was the financial trader trying to use the device.

    Chipzilla braces for a China-gaming-ban-shaped hole in future results, predicts more product delays

    Intel has blamed Apple's switch to its own M1 silicon in Macs for a dip in sales at its client computing group, and foreshadowed future unpleasantness caused by supply chain issues and China's recent internet crackdowns.

    Chipzilla's finances were robust for the third quarter of its financial year: revenue of $19.2 billion was up five per cent year over year, while net income of $6.8 billion was up 60 per cent compared to 2020's Q3.

    But revenue for the client computing group was down two points. CFO George Davis – whose retirement was announced today – was at pains to point out that were it not for Apple quitting Intel silicon and Chipzilla exiting the modem business, client-related revenue would have risen ten per cent.

  • How your phone, laptop, or watch can be tracked by their Bluetooth transmissions

    Unique fingerprints lurk in radio signals more often than not, it seems

    Over the past few years, mobile devices have become increasingly chatty over the Bluetooth Low Energy (BLE) protocol and this turns out to be a somewhat significant privacy risk.

    Seven boffins at University of California San Diego – Hadi Givehchian, Nishant Bhaskar, Eliana Rodriguez Herrera, Héctor Rodrigo López Soto, Christian Dameff, Dinesh Bharadia, and Aaron Schulman – tested the BLE implementations on several popular phones, PCs, and gadgets, and found they can be tracked through their physical signaling characteristics albeit with intermittent success.

    That means the devices may emit a unique fingerprint, meaning it's possible to look out for those fingerprints in multiple locations to figure out where those devices have been and when. This could be used to track people; you'll have to use your imagination to determine who would or could usefully exploit this. That said, at least two members of the team believe it's worth product makers addressing this privacy weakness.
