Yeah, I ended up creating a "data" class for some of the resources. Here's mine for the header:

class PSDHeaderData < BinData::Record
  ">4sH 6B HLLHH"
  endian  :big
  string  :signature, :read_length => 4
  uint16  :version
  uint8   :a
  uint8   :b
  uint8   :c
  uint8   :d
  uint8   :e
  uint8   :f
  uint16  :channels
  uint32  :rows
  uint32  :cols
  uint16  :depth
  uint16  :mode
end
