Marantz has developed a line of professional quality solid state PC card filed recorders. They have impressive features, one of which is the ability to record uncompressed PCM 16-bit audio at the sample rate 44,100 Hz. These recorders are compatible with both compact flash and ATA-size PC cards. The data is stored as a Wav audio file, which can be easily downloaded to a PC with a PC card reader. Unfortunately, the cost of a PC card capable of containing an hour of uncompressed audio is still prohibitively high, and it is uncertain whether the electronic industry will continue to be interested in developing high-capacity, inexpensive memory cards. Recently, Marantz has released a portable CD recorder, PSD 300 (PHOTO>>), which boasts the same professional features as other Marantz portables, but writes data directly to a CD-R or CD-RW. Since this is a new release, it still remains to be seen how the PSD copes with quality issues as well as the demands of fieldwork.
