    We have conducted a deep survey (r.m.s noise 17 microJy) with the
    Very Large Array (VLA) at 1.4 GHz, with a resolution of 6 arcsec, of
    a 1 square degree region included in the VIRMOS VLT Deep Survey. In
    the same field we already have multiband photometry down to
    I(AB)=25, and spectroscopic observations will be obtained during the
    VIRMOS VLT survey. The homogeneous sensitivity over the whole field
    has allowed to derive a complete sample of 1054 radio sources (5
    sigma limit). We give a detailed description of the data reduction
    and of the analysis of the radio observations, with particular care
    to the effects of clean bias and bandwidth smearing, and of the
    methods used to obtain the catalogue of radio sources. To estimate
    the effect of the resolution bias on our observations we have
    modelled the effective angular-size distribution of the sources in
    our sample and we have used this distribution to simulate a sample
    of radio sources. Finally we present the radio count distribution
    down to 0.08 mJy derived from the catalogue. Our counts are in good
    agreement with the best fit derived from earlier surveys, and are
    about 50 % higher than the counts in the HDF. The radio count
    distribution clearly shows, with extremely good statistics, the
    change in the slope for the sub-mJy radio sources.
