Frequently Asked Questions
Q. When I bring my photos, slides, 8mm film, home videos, vinyl records, tapes or other media for transfer to DVD, Blu-Ray, CD, or digital media, will my originals be damaged?
A. No. They will be returned to you intact and unharmed, just as you left them with us. Vinyl records are cleaned with our Nitty Gritty record cleaner, so they'll be returned to you nice and sparkling clean!
Q. When I bring my photos, slides, 8mm film, home videos, vinyl records, or tapes to you for transfer to DVD, Blu-Ray, CD, or digital media, are they mailed to another location, or is the work done on-site?
A. Yes. We do all our transfer work locally. Your original materials are not sent out to a remote location and will not leave the building until you pick them up.
Q. How much sound will fit on a CD?
A. CD-Rs hold up to 80 minutes of sound.
Long-playing vinyl records (12", 33 1/3 rpm) typically contain anywhere from 30-50 minutes of sound.
Q. How much video will fit on a DVD?
A. In top quality, 2 hours.
DVDs can hold up to 6 hours of video, but the more video the DVD holds, the more the overall video quality suffers. Two hours or less per DVD is recommended for top quality.
Q. What is 'flux'? / What does 'flux' mean?
A. Magnetic flux in magnetic recording tape (i. e. cassettes, videotapes, etc.)
Magnetic flux, represented by the greek letter phi, is a measure of the quantity of magnetism, taking account of the strength and the extent of a magnetic field. The SI unit of magnetic flux is the weber (in derived units: volt-seconds), and the unit of magnetic flux density is the weber per square meter or tesla.
The flux through an element of area perpendicular to the direction of the magnetic field is given by the product of the magnetic field density and the area element. More generally, magnetic flux is defined by a scalar product of the magnetic field density and the area element vector. Gauss's law for magnetism, which is one of the four Maxwell's equations, states that the total magnetic flux through a closed surface is zero. This law is a consequence of the empirical observation that magnetic monopoles do not exist or are not measurable.
