Atco55

Atco was a subsidiary of Atlantic Records founded to handle genres outside the scope of the parent label's jazz and R&B emphasis. Its first logo was a depiction of a trumpet, first appearing on 45 and 78 rpm singles in September 1955.

1957–1960 (primary), 1960–1983 (secondary)

Atco57a

Early on, the logo and label design were modified to simplify the graphic and increase the size of the Atco name. This modified design first appeared in May 1957 on U.S. 78 rpm labels. It appeared by October 1957 on 45 rpm labels, and by April 1966 in Canada. Despite being eclipsed by the 1978 logo, it continued to appear on promotional singles as late as 1983.

1957–1962 (secondary)

Atco57

When Atco began to release albums in November 1957, these featured a different label design with a depiction of a lyre. Album covers simply bore the word "ATCO," with no logo.

June–August 1959 (secondary)

Atco59

A color dot logo, conveying "full spectrum" fidelity, appeared on the covers of two 1959 LP releases: Come With Me to the Casbah by Ganimian and His Oriental Music, and Gypsy by Herb Geller and His All Stars.

Atco's first consistent logo was this stacked "ATCO" wordmark, introduced on album covers with the release of The Flying Fingers of Fliptop Finnegan in April 1960. A horizontal version was adapted for record labels in 1962, replacing the 1957 lyre logo, and continued in use until 1968.

1966–1978

Atco66

Coinciding with the parent Atlantic label adopting its box logo in August 1966, Atco adopted a new symbol consisting of a stylized record. Initially this logo appeared on album covers only, but a colorized version began to be employed on record labels in late 1968.

1978–2020

80sAtco

A refined version of the 1966 logo was introduced in late 1978, replacing the 1966 logo on album sleeves and labels and replacing the 1957 trumpet logo on 45 rpm singles (except promotional records).

By 1994, Atco's artist contracts had been shifted to East West Records; however, the Atco logo continued to appear on new releases of archival material through at least 2020. Atco was revived as an active label from 2006 to 2009, with the same logo.

In 2020, Atco was reactivated again. A new trademark was devised, combining the arched form of the 1966 and 1978 logos with the letter "A."
