IBM’s Electric Typewriter Division, later renamed the IBM Office Products Division, produced and marketed dictation devices from 1960 until 1982. This venture represented IBM’s entry into a new product category, aligned with Thomas J. Watson Jr.’s ambition to double the company’s business size every five years. Leveraging their strong presence in electric typewriters, IBM expanded into dictation equipment to broaden their product portfolio. Their objective was to provide devices that combined ease of use with superior sound quality. Although these machines complemented their typewriters, IBM’s sales team had to adjust to promoting an entirely different product line. Despite initial executive skepticism, IBM emerged as the market leader by 1965, surpassing competitors such as Dictaphone and effectively phasing out Ediphone. Sales peaked in 1969 at 98,000 units, securing approximately one-third of the market share.
Peirce Wire Recorder Company (1940–1959)
The roots of IBM’s dictation equipment trace back to Radiotechnic Laboratories, established in the late 1920s in Evanston, Illinois. In 1938, Charles Peirce acquired the company and refocused its efforts on wire recorders for the US Army by 1940, renaming it Peirce Wire Recorder Company. By 1945, they introduced the first consumer wire recorder priced at $400, capable of recording up to 60 minutes.
Although companies like Webcor and disk recorder manufacturers Audograph and Gray outpaced Peirce in the consumer market, Peirce maintained viability through an exclusive contract with the US Air Force for cockpit voice recorders. In pursuit of alternatives to wax cylinder dictation devices, Peirce developed a magnetic belt recorder that did not require sprocket holes; this innovation culminated in the 560 D model by 1955 and prompted a company name change to Peirce Dictation Systems.
In October 1958, IBM aimed to fast-track its dictation machine development by acquiring advanced technology. Peirce was the sole US-based producer utilizing magnetic media—a critical consideration for IBM. Following a market downturn in 1957/58, Charles Peirce agreed to sell patents and assets; the transaction finalized on August 15, 1959. This acquisition marked IBM’s first since purchasing Electromatic Typewriter Company in 1933. Of roughly 100 Peirce employees, IBM retained only ten; Charles Peirce remained as a consultant but was infrequently engaged. His son-in-law, Sam Kalow, joined IBM as Sales Manager and subsequently became Product Manager for dictation equipment until 1969.
IBM Executary
On October 17, 1960, the IBM Electric Typewriter Division introduced the IBM Executary Dictation Machine. The product name merges executive and secretary.
The device recorded audio onto a magnetic belt named Magnabelt—a mylar strip coated with ferromagnetic material—offering up to 14 minutes of recording time. A bar magnet allowed users to fully erase recordings within six seconds. IBM marketed the Executary as a potentially transformative innovation in dictation technology. Initially advertised as capable of being reused thousands of times and easily mailed via postal services, later promotions moderated this claim to hundreds of reuses. Subsequently, a longer Magnabelt providing 28 minutes of recording capacity was released.
IBM Executary Model 211/212/213
The three models shared dimensions of approximately 11 × 9¼ × 3¼ inches and weighed around 14 pounds; their front panels were predominantly blue unless otherwise noted. The lineup consisted of:
- IBM Executary Model 211 - Dictation Machine (6165-211), utilizing a 4-inch Magnabelt, priced at US$395.

IBM 6:5 Cartridge System (1975–1981)
Introduced in March 1975, the 6:5 Cartridge System was named for its design where each magnetic disc stored six minutes of audio and two cartridges combined allowed up to five hours of dictation. Cartridges were produced in five distinct colors such as blue, orange, and green. The industrial design was developed by Eliot Noyes & Associates. Unlike competitors relying on magnetic tape or cassettes, IBM’s approach utilized magnetic discs.
The primary models carried the IBM 6:5 branding:
- Type 281 Recorder (6164-281), priced at US $645 including microphone
- Type 282 Transcriber (6164-282), retailing at US $645 with foot pedal and headset included

Among notable users was the American Nurses Association, which employed this system for remote phone-in dictations.
A survey conducted by Management World in 1981 placed IBM fourth in the dictation market with a user share of approximately twenty-seven percent. The IBM 6:5 series was officially discontinued on December 31, 1981.
Cassette Recorder
In 1979, IBM introduced the Mini-Cassette dictation device known as the IBM Executive Recorder, manufactured by an external company in Japan. This unit weighs and offers up to 30 minutes of recording time. It can also be used as a transcription machine when paired with optional accessories such as a foot pedal, headset, and power supply. Despite these features, its audio fidelity was lower than that of rival micro-cassette devices and it was not compatible with IBM’s magnetic belt or 6:5 series models. To overcome these limitations, IBM’s Austin facility developed the dual-format transcriber (Model 292), which supported both mini-cassette and 6:5 cartridge media.
- IBM Executive Recorder Model 294 (6501-294)
- 6:5 Disk/Cassette Transcriber Model 292 (6502-292)
The mini-cassette recorder did not succeed in the market and was discontinued on September 30, 1982.
Notable Users
Lyndon B. Johnson utilized several dictation devices, including an IBM Executary, to capture telephone conversations.
Richard Nixon made use of a portable IBM Executary to document meeting discussions and kept one within reach beside his bed.
Production Facilities
IBM Lexington and IBM Canada were responsible for designing and assembling dictation machines, with additional development work carried out at IBM Austin.
In 1962, IBM Berlin (West Germany) commenced production of dictation equipment; later, in 1974, a dedicated Office Products manufacturing plant was opened there.
