1/4 inch open-reel tapes come in many formats but generally fall into two categories: “domestic tape” and “studio” tape. Both types can have a variety of playing speeds and tape lengths, giving a range of playing times as indicated in the table:
Typical spool diameters are 3.25 inch, 4 inch, 5 inch, 6 inch and 7 inch. Usually the recording speeds are either 1 7/8 ips (inches per second), 3 3/4 ips or 7 1/2 ips and they are often quarter-track (4 track) mono or stereo. Domestic reels are transcribed using either a Revox B77 deck or a Sony TC-377 deck for tapes running at 1 7/8 ips. Occasionally we receive tapes running at 15/32 ips or 15/16 ips – these are speed-adjusted using software designed for the purpose. Revox B77 Mk.II Revox B77 Mk.II
Typical spool diameters are 7 inch and 10.5 inch, and they are usually half-track (2 track) stereo recordings running at 15 ips or 30 ips. 1/4 inch Studio tape to CD transfer is performed using one of a pair of Revox B77 professional decks, catering for all speeds from 3 3/4 ips and above in both quarter- and half- track format. Often, tapes are sent to us that are encoded for dbx type 1 noise reduction – these are decoded using an outboard dbx 150 type 1 NR unit.
