XMEDA: Protože stojí za prd, hraje to hrozně a za peníze to nikdo nikdy nechtěl, navíc to u nás ani neuměli vyrábět. Já taky nějaký doma asi mám, ale i jako malej si už pamatuju, že to víc skákalo než hrálo na tom gramofonu. co jsme měli doma, co byl prostě naprd a tohle vůbec nedával..

MAR_TINA: neznici, poustel jsem si to jako malej mezi Hurvinkama a selakovyma z padesatek na starym gramoradiu a ok :) Byl tam na to i takovej kovovej kotoucek sedici presne na osku, kterym se to zatizilo.

CHROSTISTKO: Normalni desky maji presny tvrdy matrice + sam material vhodnej na desky neni uplne levnej. Tohle je proti tomu tenka PVC folie co stisknes matricema a kratce ohrejes, vali to rychle. Vetsina mono, presnost jinde, zadny hi-fi, kratka zivotnost drazek, ale na dany pouziti dostacujici. V dnesnich cenach jsi pri 5k kusu u 12" klasickych vinylu nekde ke stovce za kus, tady jsi tak u petiny. Samozrejme se u obojiho hodi, kdyz toho nadelas velky mnozstvi. Jinak dnes se vyrobci desek pomalu posouvaji k PETkam kvuli cene a spotrebe energie, takze se to tak trochu vraci k levnejsi vyrobe, jen trochu lepsi smes materialu a vetsi tloustka.

It's been quite a journey. Over 40 years ago, Dick Evans and his father developed roll fed pressing equipment fitted with record stamping dies that could produce thousands of copies every hour. Conventional record presses could make only two hundred in the same time. The vinyl discs sounded amazingly good. And they lasted for hundreds of plays.

Soundsheets were the least expensive quality recording available. Mono or stereo, one sided or two, it was economically practical to use Soundsheets where recordings had been far too expensive before. Evans created and patented assembly techniques, creating carriers that combined printed matter with the discs. And Evatone provided solutions that allowed Soundsheets to be bound into magazines and books.

Fueled by this success, Evatone grew from a dozen employees in 1960 to over two hundred by 1982. They could be handled like paper and we're perfect for use in many applications. Millions were bound into National Geographic as editorial, and into Life, Time and as a marketing vehicle in countless trade publications. Million after million were direct mailed into homes in the 1960's, 70's and 80's. McDonalds used over 17,000,000 in newspaper inserts in 1989. Educational publishers Scholastic and Weekly Reader used Soundsheets as early multimedia for the classroom, and the discs were included in Sunday School packets by many of the major Christian publishing houses for over 20 years.

XMEDA: Pokud je cena vkládané přílohy časopisu skoro dražší než sám časopis, nelze hovořit o tom, že je to levné. A mohu se zeptat: Jaký je poměr výrobních nákladů oproti vynilu? Ono obojí bude začínat galvanoplastikama...
