Transfer 1/4 inch tape to CD (up to 10 inch reels):

 

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:


Tape Playing Time


Domestic tapes:
 
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.

Studio reels: Typical spool diameters are 7 inch and (more often) 10 inch, and they are usually half-track (2 track) stereo recordings running at 15 ips or 30 ips.

1/4 inch tape to CD transfer is performed using one of a pair of Revox B77 professional decks, catering for all speeds in both quarter- and half- track format.


 

Tapes recorded at the slower speed of 1 7/8 ips are transcribed using a Sony TC-377 deck, and those rarities running at 15/32 ips or 15/16 ips are speed-adjusted using software designed for the purpose.

The quarter inch tape to CD transfer service includes attachment of leader / ender tape as necessary, as well as any simple splicing and editing which may be required prior to digital restoration and transfer to CD. More extensive repairs to broken or damaged tape, and also treatment of "Sticky Shed Syndrome" (see below) can also be carried out at extra cost; in such cases the customer would be advised on the cost and viability of restoration and transfer on an individual basis.

 

Sticky Shed Syndrome

Reel to reel tapes, especially those manufactured between the mid 70s and the early 80s, are often found to exhibit 'Sticky Shed Syndrome' (SSS) which causes serious wow and flutter, and can in extreme cases, make the tape unplayable. As the name implies, the tape 'sheds' its magnetic particles in a sticky mess onto anything it comes into contact with along the tape transit path, namely the record and playback heads, tape guides and pinch-rollers. SSS can be temporarily but effectively reversed by a carefully controlled baking process at 55 degrees C for 24 hours in our dedicated on-site laboratory oven. This process allows the recorded information to be retrieved and transferred to CD before the tape reverts back to its original condition. To prolong this reversed condition, your tape reels will be returned to you in a sealed polythene bag.

If you suspect SSS is afflicting your reel to reel tapes, do not attempt to play them. Send them to us for free assessment, and we can advise on the next move.

Broadband hiss and noise levels are reduced or removed during the transfer process.

As standard service, track separations are provided, CD text and on-CD printing are included for convenience, and your disc is returned to you in a clear, flexible vinyl wallet. 

Alternative file formats (WMA, .mp3) can also be accommodated if preferred.
