Question

40 GB memory in a camcorder is about how much recording time, what about a 60 GB?

Answer 1

Kinda depends on the format of the media.

A DVD-r is about 4g

A CD-RW is about 700mb.

[1.2] What are the features of DVD-Video?

    * Over 2 hours of high-quality digital video (a double-sided, dual-layer disc can hold about 8 hours of high-quality video, or 30 hours of VHS quality video).

    * Support for widescreen movies on standard or widescreen TVs (4:3 and 16:9 aspect ratios).

    * Up to 8 tracks of digital audio (for multiple languages, commentaries, etc.), each with as many as 8 channels.

    * Up to 32 subtitle/karaoke tracks.

    * Automatic seamless branching of video (for multiple story lines or ratings on one disc).

    * Up to 9 camera angles (different viewpoints can be selected during playback).

    * On-screen menus and simple interactive features (for games, quizzes, etc.).

    * Multilingual identifying text for title name, album name, song name, cast, crew, etc.

    * Instant rewind and fast forward (no "be kind, rewind" stickers and threats on rental discs)

    * Instant search to title, chapter, music track, and timecode.

    * Durable (no wear from playing, only from physical damage).

    * Not susceptible to magnetic fields. Resistant to heat.

    * Compact size (easy to handle, store, and ship; players can be portable; replication is cheaper than tapes or laserdiscs).

    * Noncomedogenic.

Note: Most discs do not contain all features (multiple audio/subtitle tracks, seamless branching, parental control, etc.), as each feature must be specially authored. Some discs may not allow searching or skipping.

That was from 2003,,so maybe stuff has changed...

Here is a chart:

The most common discs are the DVD-5 stamped discs.  They can hold 4.7 Gigabytes of information per side, which is about 133 minutes of MPEG-2 video/audio. However this varies greatly, due to the data rates of the MPEG2 video and audio streams (the amount of compression), and whether or not there are menu's, extras, chapter points, subtitles, etc.

Both CD’s and DVD’s store information in the form of engraved pits on its surface to represent the digital information ( 1's & 0's ), which is read by a laser.  Only the DVD manufacturers create engraved pits (sometimes called “stamping”).  PC burned DVD’s use a reflective dye and the laser “burns” the data into.  However, although the processes are entirely different - the resulting storage capacity is the same.

NOTE:  actually, the manufacturers “say” 4.7 GB, but they use the metric system to come up with this number, which artificially inflates the actual capacity, since most people think they are quoting a binary value.  They use kilo=1000 instead of the computer kilo=1024.  The actual capacity = 4,707,000,000 Bytes = 4,489 MB = 4.38 GB

Also a few years old,,,but is very very close.

Now it falls back to Quality and Format. Size also matters. 780x56 is not the same as 800x1200,,also note:

It's very common to store information on both sides of the disc resulting in a total double sided capacity of 9.4 Gigabytes. Some movie companies make use of this facility by placing a Widescreen Transfer of the film on one side & a Standard version of the film on the other. Others throw in extras on the other side.
