Just last weekend, amandaghassaei published her Laser Cut Record. The work is more than great with a tons of experimentations and descriptions! However, thorough these days, we also prepared to publish our version of Laser Cut Record with prior acoustic information as a part of our "cutting record - a record without (or with) prior acoustic information" project at IAMAS. To be honest, the work is still in its experimental stage and very close to amandaghassaei's work. But we decide to publish it to stimulate the scene (Hope it exists!) and further investigations with a lot of common points and a few differences especially in our codes. Here is our version.

Step 1: Laser Cut Record (version)

As amandaghassaei mentioned, we've already have an instructables of "How to make a record without prior acoustic information" to make an analog record with laser cutter and paper cutter. We've explained the background of our project (include history of analog record) at there. So, here, we simply describe our process with prior acoustic information by following/comparing amandaghassaei's instructables.

The records were cut on a Universal 30 Watt VLS 2.30 with HPDFO (High-Power Density-Focusing Optics) lens  to a theoretical precision of 1000dpi. The bit rate / sampling frequency of the original audio data is 16 bit / 44.1kHz but you could just listen the result around 8 bit / 12 kHz (the number is not well measured, but you could listen the quality) because of the melt on a material by laser beam and the motion of stepping motor (we guess). We've wrote a custom application with Processing to generate a spiral groove with peripheral circle and a center hole in a form of SVG file based on given audio data. The application provides parameters of diameter, sampling rate, rpm, amplitude, line space, and margin for adjustment. The resulted SVG file could be imported in other vector graphics software (e.g Adobe Illustrator, Corel Draw) for laser cutting. We also develop a way to produce a locked groove with audio data without coding, you could see the way at the end of this instructables.

You could see more information at Kazuhiro Jo and Mitsuhito Ando, cutting record - a record without (or with) prior acoustic information, Proceedings of NIME (New Interfaces for Musical Expression) 2013 , 26th-30th, May, 2013 (to be published).

Laser Cut Record - Daisy Bell

Laser Cut Record - Smells Like Teen Spirit


I watched a Doco about a small Japanese company that developed a high quality laser vinyl player. They Cost a pile of money and sold to archives that digitise super rare fragile ye olde phonographic records. Ive had the laser turntables stuck in my head ever since . Ive been researching vinyl lathes for ages . They cost a fortune to setup and maintain for average results. I cant believe the laser cut vinyl concept works . Ill be keenly following the progress . i hope i can catch up so i can contribute to improving this technology. Ive got so many wicked beats that need to be cut. Timecode vinyl is fun cor a bit but analogue sounds superior , better to mix with etc. Sorry for the life story everyone ,im just f**kn excited . cheers
<p>Hi,<br></p><p>I have the same probleme of Koos007<br></p><p>I using the software Processing 3;1.2 64 bit on w10 because Processing 3.2.1 don't work correctly on W10.</p><p>Witch version of Proccesing work correctry with CuttingRecordGenerator.pde?</p>
<p>Hello, The idea is great. I year ago, I believe, It worked for me. but now I'm stuck in the process... Processing (3.2) gives a error (NullPointerException) in de code when processing. Hope someone can help me. Thank you very much when possible!</p>
<p>Should have played &quot;Daisy&quot; at 33 1/3 rpm for the obvious reference.</p>
Nice! <br>Voted on this Project, and went to this Blog-Post: <br>http://faz-voce-mesmo.blogspot.pt/2013/05/handibot-cnc-nas-obras-e-mandem-vir.html
looks great! thanks for your post!
I like to give attribution, and it's fun to collect neat stuff, like that. :)
Vinyl ressurection? WOW Nothing new under the Sun
please resurect your own!
I love Vinyl records, I hope you get a great sounding record at the end. <br>Great job!!
thanks! we also hope so! <br>
Needs a run-out groove.
good idea! will add the function. thanks for your suggestion!
I know this will be a lot of work, but I think you'd get better sounding records if a cylindrical coordinate system is used rather than cartesian. Nice to see more than one person approaching the problem though!<br/>Could some sort of mask be fashioned with a tiny aperture lying close to the disk, to improve resolution?
Thanks for your suggestion! We'll try and let you know the results. Sorry for the resolution ;-)
