The webmaster has the following equipment at his disposal to digitize or transfer / capture several different formats.

Magnetic media

Audio cassette tapes

Nakamichi Dragon

  • Three head, asymmetrical dual direct-drive capstan transport with pressure pad lifter
  • Automatic playback azimuth adjustment, yielding best frequency response of a tape that was recorded on any other device
  • Upgraded with Maxim MAX4066 CMOS switches for improved sound quality over the factory 4066 chips, with additional voltage translation circuit to maximize benefit of better switches
  • Professionally serviced by Perry, involving new belts and idler tire, full clean, relube, and alignment, as well as incorporating all the beneficial upgrades done from the factory on later serial number Dragons based on the service manual, including upgraded and up-rated power supply capacitors. Several other capacitors were also replaced, and the tape auto-stop sense bulbs were replaced with LEDs for reliability. This Dragon is serial number 4964.

Digital Audio Tape (DAT)

Sony SDT-9000 SCSI DAT drive

  • Flashed with firmware that is able to read audio DATs
  • Most direct option to rip audio DATs to WAV format in their native sample rate (i.e. 16-bit 32khz / 44.1khz / 48khz)
  • Allows error correction which no standalone DAT deck / recorder can perform
  • Regularly cleaned according to manufacturer recommendations using "new old stock" Seagate DAT head cleaning tapes
  • DATs ripped using dat2wav software

VHS / S-VHS

PAL

  • Philips VR1000 (JVC rebadge; for PAL tapes) with built-in line time base corrector
  • DataVideo TBC-1000 full-frame time base corrector
  • ATI All-In-Wonder 9600XT AGP video card for lossless Huffyuv AVI captures, captured on a dedicated Windows XP Service Pack 2 computer
    • Other general computer specifications: HP Compaq d530 CMT computer with Pentium 4 Extreme Edition 3.2ghz with HyperThreading, 1.5GB DDR-400 RAM, 80GB Western Digital Velociraptor + 500GB Western Digital Blue hard drives, Creative Sound Blaster X-Fi XtremeMusic, Microsoft Windows XP Service Pack 2
  • Audio captured at PCM 16-bit 96khz using Monoprice Premium 6 foot RCA to 3.5mm 22AWG gold plated cable to Creative Sound Blaster X-Fi XtremeMusic sound card

I am still working on obtaining a high-end NTSC S-VHS VCR.

Optical Media

Compact Discs / CD-R

DVD

BD

  • Not applicable at this time due to no Blu-Ray bootlegs existing that need to be ripped; as far as I know, only one or two BD recordings have been torrented on DIME

MiniDisc

Sony MDS-S707 MiniDisc deck

  • Optical output is used for digitally bit-perfect captures
  • Many thanks to Ryan Jonik for his generous contribution of the MD deck

Vinyl / LP

Audio-Technica AT-LP120-USB Direct-Drive Professional Turntable + Shure M97xE Cartridge
