Re: [ARSCLIST] CLIR document/ Leader
Has anyone run into problems with different types of leader (i.e. Radio
Shack, or the stuff the BBC was adding to Zonal in the 80s) being very
sticky? I've had no trouble with the conventional stuff from 3M, Audio
Devices or AGFA, and besides, it serves a purpose (timing pauses before and
between tracks).
The paper stuff is useful when something is needed between the end of the
tape and the hub of the reel..I find it's much less prone to taking the
shape of the hub's openings. But I also find that over the years, splices
won't stay attached to it.

Hi,
As I recall, general wisdom in ARSC suggests that
for archives the use of NO leader tape at all has
always been recommended for tapes to be stored,
since attaching leader(s) involves the use of
splicing tape, another material to be avoided as
much as possible. Obviously one must deal with
splices that come in on tapes; but except for
attaching leader or blank tape temporarily to
allow capture of beginnings and endings on
recordings lacking sufficient unrecorded "slack", why ask for trouble ?
