A series of technical reports on data storage devices originally developed by Freeman Associates, Inc., Santa Barbara, CA (www.freemaninc.com). For more than two decades, they provided exhaustive detail about the disk and tape industry, including up-to-date data on technology, capacities, purposes, market share and future trends. In 1999, Freeman Associates discontinued the series, but turned over the tape market research and reports to Freeman Reports, Ojai, CA (www.freemanreports.com).
