Digalog cassettes

I picked up the Foo Fighters - There is nothing left to lose on Digalog cassette and have to say that it sounds fantastic. I believe these tapes used a quality cobalt formulation.

It means that the cassettes were made from a digital master.

Loop bin duplication

"Digalog"--an amalgam of digital and analogue--is a trademark of the WEA (Warner/Electra/Atlantic) group that had duplication facilities in Olyphant, PA, (Specialty Records) and Los Angeles, CA, (Allied). WEA used Concept Designs' digital bins feeding slaves enabled with Dolby HX. The vast majority of the tape was BASF LH-D, the basic Type I ferric noted for excellent consistency and low rub-off. Other tape could be SKC or Aurex ferric tapes.

Later cassette tapes are recorded from digital master bins, therefore they have a more digital-like sound, e.g. crisper and sterile, sound characteristics that are associated with digital sound. This happened in the mid 80's. (around that time)

Digalog (off Techmoanís video)

Hi everybody from a long-time (1982-2010) FM-to-cassette archivist. Iíve since jumped the fence to Audacity/iTunes AAC128 kbps mainly because of lack of space and indexing.

Does anybody have specifications related to Digalog? Here is my understanding of it:

16/44 digital audio is bin-duplicated at 8x, meaning the DACs operate at 3.528 MHz (at 12 or 14 bits?) and the recording head replaces the low-pass filter to reconstruct the analog audio directly on the magnetic tape. This process perhaps cancels the need for bias because of the audio images in the unfiltered audio, or perhaps at 8x, the amount of HF-energy is so high as to self-bias the recording.

Is this credible?

Rather than PCM, the heads are driven by PWM -almost like a class D amplifier or the DSD signal on a SACD, and yes, it's plausible enough that some random dude on YouTube managed to record on a cassette using nothing more than a modified 555-timer circuit.

The source material was likely CD (16/44) or DAT (16/48) depending on how it was mastered, but once it's converted to PWM or DSD the effective bit depth has no clear correspondence to the original PCM material anymore, as the way of converting is not unique. In any case, it sounded good, which is what mattered

I am not sure how the "digital bin" works. There are several methods anyway, each to every manufacturer.
AFAIK, all of them used DACs inside, 4 of them (all channels are written at once), then the filters and finally the recording system (head). Bias is to my knowledge still present. Even Dolby is created digitally on some systems (CBS for instance). Some of them use arrays of RAM cells, other use arrays of optical discs, some use HDDs - practically every digital storage technology has been used to intermediary store the music, once the videotape has been "retired" from use.

There is no self-biasing or anything like, since the bandwidth is controlled (10khz, 15khz) and the speed cancels the high-frequency influence.

Digital makes sense when viewed through the eyes of business.

The music business has buried itself.

"It all makes perfect sense, expressed in dollars and cents"

"Radio friendly unit shifters" LOL

The irony is, they have to embrace analog, if they want to sell any music.

I can't say I avoided them at all. Quite the opposite, I EMBRACED them as a whole. Compared to the previous generations of cassettes, these sounded and performed leagues ahead, almost like a gift from the audio gods. In fact these tapes were SO good, they kept me from switching over to digital anything in my competition audio cars as well as the others I owned. I believe that the old-school analog/digital cassettes, and cassette as a whole gave my system's an edge over others..

Wait, don't we do something similar to digilog today, use high resolution digital sources to record on Analog tape (open reel) with outstanding results, albeit at 1:1 speed??..

I will say however, the cassettes I used then, I still own and use, a great number of them were the DigiLog releases, or some very similar with HX Pro, all store bought, though I did make my own custom mix cassettes on Type I and II cassettes. I found overall Type I was better for the car. CD just didn't do it in the cars or trucks I built audio systems for and didn't put a CD player in anything I owned, or buy a car or truck with one until I got my Durango, and later on my wife's first Cadillac. The Durango to it's credit sounded very nice for a stock system albeit one with Infinity Drivers and Amps separate from the head unit.



The Digilog cassettes (I made a post about them similar to this one several months back) to my ears at least on my gear have always sounded the best out of all the releases on pre recorded cassette. Now let me qualify and clarify that, I am speaking of popular releases strictly, not the specialty or Classical music releases. I can not speak to their quality on Digilog or otherwise. Other music,.., Country, Pop, Disco, Rap, Blues, Rock, if I had my druthers between buying CD back in the day probably today if someone (like MoFi, or Chad Kassam over at Quality Records (QRP) released Digilog recorded cassettes), were to begin selling them made similar on duplication machines designed similar to the way Nakamichi did with their better cassette transports, I'd quit buying CD's for the most part. If he began selling open reel pre records, the same applies, but to Cassette CD, and in most cases LP. That is another story for another day.

In the meantime I'll enjoy the Digilog releases, and buy them wherever and whenever I can.... the less that folks that like them, the more there are for me.....

This is nonsense. Analogue flaws of the cassette medium itself are greater than any flaws of the digital source. The alternative to a digital bin was a master tape recorded at 3.75 ips--the lowest speed that barely makes the high fidelity cut--and run to death in a high-speed bin. That may be the preference for those who like a double-dose of harmonic distortion, modulation distortion, noise, and limited frequency response; but it was what the recording engineers were trying to avoid in order to present a cassette copy as close to the stereo master tape as possible.

Looks to me like they do it in reel time when in studios, and at half speed when cutting vinyl......

We're going to make your cassettes in seconds from a digital master........because,

Hehe ya Cary...... I wish I could have talked to these people directly and tell them to stop forcing this garbage on people!!!

Digital is flat,sterile crap and I dont want it.... WHY DO THEY THINK I DONT GET DIGITAL MEDIA??


I'd love to have been able to tell them to take thier digital crap and shove it up thier ass!!

They dug their own grave.

No more all night coke parties with rock stars.......

Even store employees at Tower were partying like rock stars!

They tapped every penny they could and now it's all bust.

My kids own NO physical media!!!!!

Hollywood is next!!!!!!!!!!

They took the best part of music, the emotion, and tossed it in the garbage.

I bought a 45 rpm double LP and it sounded lifeless. Digital master from one of the best guys in the business.

A 45 rpm from a 50 year old tape kills it all day long.

MQA is supposed to be the next band aid for digital.

We will see..........

Until than, I just bought another 505.

Money in the bank......

Go to the compact disc section or ones and zeros.

That's your "safe space"

I rarely post in there, however less than a year ago when you got a new Cary DAC you claimed, "It's so good that I stopped listening to records. Has the attributes of vinyl but with a black background."

What changed? Now digital is the worst thing ever? What will you say another year from now? DSD is the best?

Upgraded my amplifier. Bought a CR-7. Bought some NOS chrome and metal tapes. Bought a Teac X2000R. Heard a copy of a master tape. Bought some 45 rpm re-issues.

In analog you chase the sound because it can be improved on, digital is free so it is what it is.

To quote David Geffen, "No one would buy Coke if it came out of your tap for free"

There you go.

There's a very real reason why all this stuff is going up in value.

A NOT MINT Dragon went for 2550 last week.
