How do you figure that tapes are less expensive than digital? I have a feeling that if you compared the cost (and inflexibility, and speedy degradation) of analog cassette tape with that of digital audio, you might be in for a surprise. For example, at tape.com, they sell a 100 pack of 62-minute cassette tapes for $30. Not too bad. They sell a 100 pack of 80-minute CDs for $17.50. That would seem to make digital less expensive, at least with respect to removable media.
I haven't figured out the math myself, but according to
Cakewalk, uncompressed, stereo, CD-quality audio at 16-bit/44.1 KHz requires 10.3 MB/minute. Mono requires 5.2 MB/minute. Let's be conservative and assume that you are recording in stereo.
A 500 GB Western Digital hard drive costs $125 at
Newegg.com right now. Because hard drive manufacturers use a different measure of gigabytes than the rest of the computing world, this comes out to more like 465.6 GB. So, let's break this down on a per minute basis.
Cassette tape = 206.6 minutes per dollar (with 62-minute tape)
Cassette tape = 264.7 minutes per dollar (with 90-minute tape, 100-pack at $34)
Hard Disk = 370.3 minutes per dollar
CD = 457.1 minutes per dollar
So, CDs win the minutes per dollar award. Cassette tapes, at 90 minutes a piece, cost about 40% more per minute than hard disk, if I've done my math correctly. What's more, 100 cassette tapes take up a lot of space and audibly break down in just a few years. 100 CDs take up less space and have a better archival life, but are still less than convenient. A 500 GB hard disk isn't much bigger than two slices of bread. It supports random access to all of the files on the disk and can be searched by freely available utilities. Note, if you compress your audio with an MP3 encoder, the digital media become even cheaper, by 4 to 8 times. I also did not account for a 4-track, in which case your 90-minute tape becomes a 45-minute tape.
100 tapes (at 90 minutes) can hold 9,000 minutes of music.
100 CDs can hold 8,000 minutes of music
1 hard drive (at 500 GB) can hold 46,289 minutes of music.
I'm afraid that the economic argument does not hold up here, neither does one based on archival life, ease of access, or ease of storage. If you are already setting up a four track and mics, you could do things with your computer almost as easily, provided the 1-minute boot time would not get in the way.
Just some food for thought.
