snowwillow is correct.
I've been using my Sony HDR-HC1 for about 5 years - and I rarely re-use tapes. Each 60 minute tape can hold up to 63 minutes of HDV format video. I have over 300 in a few shoe boxes. I have used a head cleaning tape 2x (when the error message appeared, I ran the cleaning tape according to instructions - only 10 seconds).
And the camcorder keeps recording and being the "import deck" for computer transfer... So... at least 600 hours (likely more) capturing and playing back (for importing) and connecting to a HDTV for high def view/capture review...
A regular miniDV standard definition deck won't work - it needs to be able to handle HDV. Sony has a consumer HDV deck - check the GVH-D700. Cheaper just to get another HDV camcorder... The pro HDV decks cost more.
And the "DV" in miniDV = Digital Video. Just because the zeros and ones are written to tape does not make the video somehow less digital. It certainly is NOT analog (like VHS, BETA or 8mm) and is just as digital as flash memory, hard disc drive or DVD is digital. BUT the advantages MiniDV has over those other consumer storage methods includes - but is not limited to:
==> DV and HDV format video is much less compressed than the video stored to consumer flash memory, hard disc drive or DVD storage media. More video compression = more discarded data = reduced video quality.
==> miniDV tape has the longest known shelf life (for archiving video) when compared to the other consumer storage media. Just don't re-use the tapes.
==> miniDV tape has the lowest $/gig storage so it continues to be the most cost effective and affordable media.
There's more... but just remember that the professionals typcally gravitate to the "best available"... so... Check the equipment they use:
Canon XH series and XLH series
Sony HVR series
Panasonic AG-HVX series
JVC GY-HM series
*Most* of these use miniDV tape. Those that do not (Sony HVR-Z7, Panasonic AG-HVX200, JVC GY-HM100) use flash memory - and record to DV/HDV. There are no prosumer or pro grade camcorders that use an internal hard drive - and those that use an external hard drive (like the FireStore series from Focus Enhancements) wirte to DV/HDV... No anemic AVCHD like that found in consumer camcorders.
