The four track (4tk) cartridge is an unfamiliar item to most music listeners today. It was invented shortly before the eight track cartridge, but for some reason it never attained the popular appeal that the eight track did. A four track cartridge might be mistaken for an eight track, the most visible difference between the two being a hole in the cartridge approximately 3/4 inches in diameter. Four tracks manufactured for Capitol before 1969 also feature transparent front shells, making them readily distinguishable from eight tracks for those who know that four tracks existed.
Earl "Madman" Muntz was the chief producer of four track cartridges, having purchased the right to do so in order to equip his cars with tape machines. By 1963, the four track was on the horizon as the successor to reel tapes and singles players -- at least as far as the automobile was concerned. Double four tracks, which measured approximately 6" wide by 7" deep, were also produced for a short season, but the standard size single-album cartridge soon became the standard. For several years, cartridge players were made that were "four/eight compatible." Finding such a player today is a rarity. I know of no company that has manufactured four track players in the last twenty years. This is unfortunate, since the four track was an interesting format.
Four tracks play at 3¾ inches per second, as do eight tracks. However, being in stereo, they only have two programs. This provided an advantage over the eight track of seldom having a song split between two programs. As every 8 track buyer knows, this was a major annoyance with the eight track. Four tracks seldom had this problem. The big disadvantage to the four track, which made the eight track an improvement, was the fact that one roller was part of the machine and came up into the hole in the back.
Capitol Records seems to have picked up on four tracks some time in
1964. Cartridges that Muntz produced for Capitol before late 1965 differ
from later copies slightly. For example, if you look at the back of the
cartridge, the earlier cartridges have a corner
hole next to the hole for the capstan (upper left hand corner).
Cartridges from late 1965 onward have only the round
capstan hole in that corner. There are also other
slight design differences. Still later (late 1967 on), the front of the
shells were made in transparent or translucent colors (pink, brown, etc.)
instead of clear.
Capitol never made their own four tracks. Until mid-1969, they licensed out
to Muntz Stereo-Pak in Van Nuys, California. On these four tracks, the
statement "not affiliated with Muntz T.V." appears. Then in early Fall '69,
Capitol contracted with Ampex Tapes to manufacture both its reel tapes
and its four tracks. Since Capitol switched from their traditional dome
logo to the new "C" logo in June, 1969, this means that copies which feature
the new logo are harder to find. Also, these
copies feature new (colored) shells which have "rib grips" on the sides,
making them easier to extract from four track machines.
Tapes made by Ampex have tan or yellow colored shells.
All Capitol four tracks prior to early-mid 1969 appear to have been housed in the same white boxes. Those made during 1969 by Muntz have black and red boxes. The boxes for Ampex tapes tended to have the contents printed on the back. Ampex four tracks made for Apple featured their own Apple boxes.
Four tracks and reel tapes seem to have perished at the same time (for Capitol), although the reels MAY have lasted longer. Beatles related (Ampex) four tracks do not seem to have been manufactured after 1970. Since the last known Beatles related reel tape was issued in 1971, it may have been that there were some four tracks also issued that year. If that is the case, then the later four tracks are simply harder to find.

As mentioned above, all of the Capitol 4 tracks are found with the Capitol "dome logo", which was in use until June, 1969. Not all of them have yet been discovered to carry the new "C" logo, but these are certainly scarcer, having been made for about 2 or 3 months at most.

NOTE: It seems that all of the mainstream Capitol four tracks were reissued when the tape catalog switched to Ampex in 1969. The following tapes, with yellow or tan shells, have been verified to exist:
| Beatles Second Album | Capitol/Ampex X 42080 |
| Beatles '65 | Capitol/Ampex X 42228 |
| Sgt. Pepper's Lonely Hearts Club Band | Capitol/Ampex X 42653 |
| Magical Mystery Tour | Capitol/Ampex X 42835 |
| The Beatles | Apple/Ampex M4 101/M4 2101 |
| Yellow Submarine | Capitol/Ampex X 4153 |
| It appears that these reissues are scarcer than the original releases. | |
The following tapes were all made by Ampex unless indicated. Therefore, they all have tan shells and an outer title box (with a large Apple), unless indicated.
| Abbey Road | Apple X 4383 |
| The above does not list "Her Majesty". Does a Muntz version exist? | |

One non-Beatles Apple four track is known (so far). This is Mary Hopkin's Post Card, Apple 4CL-3351. Sealed in its Apple/Muntz outer box, a copy recently sold for $192.50.
The four track passed on in favor of the eight track, which in turn was to die in favor of the cassette. Most Beatles four tracks go for $50-$60 in their appropriate packaging. The ones having two cartridges usually fetch $75 or more. "C" logo copies and Ampex reissues of the earlier Capitol LP's are scarce and should sell for $75 or more as well. The very rare Ain't She Sweet album goes for over $500.
